The embeddings endpoint is now permanently fixed to /embed with no user-configurable path option. This removes unnecessary configuration surface since the feature has not been released yet, eliminating the need for backward compatibility. Changes: - Remove path property from dab.draft.schema.json - Remove Path, UserProvidedPath, and EffectivePath from EmbeddingsEndpointOptions - Remove EffectiveEndpointPath from EmbeddingsOptions - Remove path deserialization from EmbeddingsOptionsConverterFactory - Remove --runtime.embeddings.endpoint.path CLI option - Remove path configuration logic from ConfigGenerator - Remove endpoint path validation from RuntimeConfigValidator - Update Startup.cs logging to use DEFAULT_PATH constant - Update all tests to remove path references --- schemas/dab.draft.schema.json | 5 - src/Cli.Tests/ConfigureOptionsTests.cs | 54 +---- src/Cli/Commands/ConfigureOptions.cs | 5 - src/Cli/ConfigGenerator.cs | 18 +- .../EmbeddingsOptionsConverterFactory.cs | 6 +- .../Embeddings/EmbeddingsEndpointOptions.cs | 25 --- .../Embeddings/EmbeddingsOptions.cs | 6 - src/Config/ObjectModel/RuntimeOptions.cs | 2 +- .../Configurations/RuntimeConfigValidator.cs | 37 +--- .../UnitTests/ConfigValidationUnitTests.cs | 114 ---------- .../UnitTests/EmbeddingControllerTests.cs | 201 +++++------------- .../Controllers/EmbeddingController.cs | 23 +- src/Service/Startup.cs | 2 +- 13 files changed, 67 insertions(+), 431 deletions(-) diff --git a/schemas/dab.draft.schema.json b/schemas/dab.draft.schema.json index 9287ec9fa5..a6fadd9d0e 100644 --- a/schemas/dab.draft.schema.json +++ b/schemas/dab.draft.schema.json @@ -710,11 +710,6 @@ "description": "Whether the /embed REST endpoint is enabled.

This causes two problems: - Some logs appear even when LogLevel is set to some value that would impede those logs to appear. - Some logs don't appear at all, even when LogLevel is set to a value that should allow them to be logged. - Closes issue #3256 & #3255 The CLI logger still outputs some logs even when the LogLevel is set to `none`. It is expected that if the LogLevel set is `none` or some other level that shouldn't output the `information` level, the logs will not appear. ## What is this change? Important Note: These changes currently only allow us to change the LogLevel from the CLI with the `default` namespace in the config file. An task was created to solve this issue: https://github.com/Azure/data-api-builder/issues/3451 In order to solve issue #3262: - We removed the LogBuffer from the services inside of `Startup.cs`, this is necessary since we wanted each class to have its own LogBuffer so that we are able to tell from which logger the logs are being outputted. - Then, we also correctly initialized the `Startup` logger by changing the method that it was using to initialize the logger, it now uses `CreateLoggerFactoryForHostedAndNonHostedScenario` which checks if there are any LogLevel namespaces from the config file that can be applicable for the specific logger. It is important to note that there are multiple places where the logs are flushed in order to cover for the cases in which an exception is found and causes DAB to end abruptly, and when we there is an IsLateConfigured scenario. - We also changed the logger for the LogBuffer in all the missing places where it creates logs before the logger is able to properly initialize to add those logs to the LogBuffer and only flush them after the loggers are initialized. In order to solve issue #3256 & #3255: - We changed the CLI so that we add all the logs go to a single global LogBuffer that is created inside the `StartOptions.cs` until it is able to deserialize the RuntimeConfig and find which level to set the `LogLevel` in order to flush all the logs. - This is something that we only want to happen when we use the `dab start` command, which is why we only make this change in the `StartOptions.cs` file, on the function `TryStartEngineWithOptions` inside of `ConfigGenerator.cs`, and a few functions from `Utils.cs` and `ConfigMerger.cs` that are used inside the `TryStartEngine` function. ## How was this tested? - [ ] Integration Tests - [x] Unit Tests ## Sample Request(s) - dab start --LogLevel none - dab start --LogLevel error --------- Co-authored-by: Aniruddh Munde * Update config validation logic for entities (#3306) ## Why make this change? Closes https://github.com/Azure/data-api-builder/issues/3267 ## What is this change? Alters the validation logic in the following way. Is top-level config with data-source-files? (we call this a `Root` config file) ├── YES │ ├── Has datasource? → ValidateEntityPresence (same rules as non-root) │ ├── No datasource but has entities/autoentities? → ERROR │ └── No datasource, no entities → VALID (children provide everything) │ └── For each child → ValidateNonRootConfig(child, filename) │ └── NO (standalone or child config) ├── No datasource? → ERROR: "data source is required" └── Has datasource → ValidateEntityPresence Note: A top-level config file without any children data-source files is NOT considered a root. And an intermediary config file, ie: is a child, that also has child configs is NOT a root. Only a top-level config with children configs is a Root. #### ValidateEntityPresence Count resolved autoentities from AutoentityResolutionCounts total = manual entities + resolved autoentities total == 0? → ERROR: "No entities found" total > 0 but autoentities discovered nothing? → WARN: "Autoentities configured but none discovered" No double messaging. If total is 0, only the error is recorded, not the warning. ## How was this tested? ### Truth table — top-level config Variables (`1` = present / non-empty, `0` = absent / empty): - **DSF** — `data-source-files` present - **DS** — `data-source` present - **E** — manual `entities` count > 0 - **AE** — `autoentities` count > 0 (presence, *not* resolved count) Path is determined by

This causes two problems: - Some logs appear even when LogLevel is set to some value that would impede those logs to appear. - Some logs don't appear at all, even when LogLevel is set to a value that should allow them to be logged. - Closes issue #3256 & #3255 The CLI logger still outputs some logs even when the LogLevel is set to `none`. It is expected that if the LogLevel set is `none` or some other level that shouldn't output the `information` level, the logs will not appear. ## What is this change? Important Note: These changes currently only allow us to change the LogLevel from the CLI with the `default` namespace in the config file. An task was created to solve this issue: https://github.com/Azure/data-api-builder/issues/3451 In order to solve issue #3262: - We removed the LogBuffer from the services inside of `Startup.cs`, this is necessary since we wanted each class to have its own LogBuffer so that we are able to tell from which logger the logs are being outputted. - Then, we also correctly initialized the `Startup` logger by changing the method that it was using to initialize the logger, it now uses `CreateLoggerFactoryForHostedAndNonHostedScenario` which checks if there are any LogLevel namespaces from the config file that can be applicable for the specific logger. It is important to note that there are multiple places where the logs are flushed in order to cover for the cases in which an exception is found and causes DAB to end abruptly, and when we there is an IsLateConfigured scenario. - We also changed the logger for the LogBuffer in all the missing places where it creates logs before the logger is able to properly initialize to add those logs to the LogBuffer and only flush them after the loggers are initialized. In order to solve issue #3256 & #3255: - We changed the CLI so that we add all the logs go to a single global LogBuffer that is created inside the `StartOptions.cs` until it is able to deserialize the RuntimeConfig and find which level to set the `LogLevel` in order to flush all the logs. - This is something that we only want to happen when we use the `dab start` command, which is why we only make this change in the `StartOptions.cs` file, on the function `TryStartEngineWithOptions` inside of `ConfigGenerator.cs`, and a few functions from `Utils.cs` and `ConfigMerger.cs` that are used inside the `TryStartEngine` function. ## How was this tested? - [ ] Integration Tests - [x] Unit Tests ## Sample Request(s) - dab start --LogLevel none - dab start --LogLevel error --------- Co-authored-by: Aniruddh Munde * Update config validation logic for entities (#3306) ## Why make this change? Closes https://github.com/Azure/data-api-builder/issues/3267 ## What is this change? Alters the validation logic in the following way. Is top-level config with data-source-files? (we call this a `Root` config file) ├── YES │ ├── Has datasource? → ValidateEntityPresence (same rules as non-root) │ ├── No datasource but has entities/autoentities? → ERROR │ └── No datasource, no entities → VALID (children provide everything) │ └── For each child → ValidateNonRootConfig(child, filename) │ └── NO (standalone or child config) ├── No datasource? → ERROR: "data source is required" └── Has datasource → ValidateEntityPresence Note: A top-level config file without any children data-source files is NOT considered a root. And an intermediary config file, ie: is a child, that also has child configs is NOT a root. Only a top-level config with children configs is a Root. #### ValidateEntityPresence Count resolved autoentities from AutoentityResolutionCounts total = manual entities + resolved autoentities total == 0? → ERROR: "No entities found" total > 0 but autoentities discovered nothing? → WARN: "Autoentities configured but none discovered" No double messaging. If total is 0, only the error is recorded, not the warning. ## How was this tested? ### Truth table — top-level config Variables (`1` = present / non-empty, `0` = absent / empty): - **DSF** — `data-source-files` present - **DS** — `data-source` present - **E** — manual `entities` count > 0 - **AE** — `autoentities` count > 0 (presence, *not* resolved count) Path is determined by `IsRootConfig = (DSF == 1) && !IsChildConfig`. | #

Enables MCP clients (like MCP Inspector, Claude Desktop, VS Code Copilot) to receive real-time log output via MCP `notifications/message`. Related: #3274 (depends on PR #3419) ## What is this change? When `logging/setLevel` is called with a level other than "none", logs are sent to MCP clients as JSON-RPC notifications: ```json { "jsonrpc": "2.0", "method": "notifications/message", "params": { "level": "info", "logger": "Azure.DataApiBuilder.Service.Startup", "data": "Starting Data API builder..." } } ``` ### New files: - `McpLogNotificationWriter.cs` - Writes logs as MCP notifications to stdout - `McpLogger.cs` / `McpLoggerProvider.cs` - ILogger implementation for .NET logging pipeline - `McpLogNotificationTests.cs` - Unit tests (8 tests) ### Modified files: - `Program.cs` - Registers `McpNotificationWriter` and `McpLoggerProvider` for MCP mode - `McpStdioServer.cs` - Enables notifications when `logging/setLevel` is called ## How was this tested? - Unit tests: 6 tests covering level mapping, enable/disable, JSON format - Manual testing with MCP Inspector: verified notifications appear when `logging/setLevel` is sent ## Note This PR targets `dev/anushakolan/set-log-level` (PR #3419) as it depends on the `logging/setLevel` implementation. --------- Co-authored-by: RubenCerna2079 <32799214+RubenCerna2079@users.noreply.github.com> Co-authored-by: Aniruddh Munde Co-authored-by: aaronburtle <93220300+aaronburtle@users.noreply.github.com> Co-authored-by: Anusha Kolan Co-authored-by: Sayali Kudale Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../Core/McpStdioServer.cs | 56 +++-- .../Core/McpStdoutWriter.cs | 101 ++++++++ .../Model/McpStdioJsonRpcErrorCodes.cs | 5 + .../Telemetry/McpLogNotificationWriter.cs | 114 +++++++++ .../Telemetry/McpLogger.cs | 126 ++++++++++ .../Telemetry/McpLoggerProvider.cs | 58 +++++ src/Core/Telemetry/McpLogLevelConverter.cs | 70 ++++++ .../UnitTests/DynamicLogLevelProviderTests.cs | 82 +++++++ .../UnitTests/McpLogNotificationTests.cs | 232 ++++++++++++++++++ .../UnitTests/McpStdoutWriterTests.cs | 229 +++++++++++++++++ src/Service/Program.cs | 47 ++++ .../Telemetry/DynamicLogLevelProvider.cs | 25 +- 12 files changed, 1104 insertions(+), 41 deletions(-) create mode 100644 src/Azure.DataApiBuilder.Mcp/Core/McpStdoutWriter.cs create mode 100644 src/Azure.DataApiBuilder.Mcp/Telemetry/McpLogNotificationWriter.cs create mode 100644 src/Azure.DataApiBuilder.Mcp/Telemetry/McpLogger.cs create mode 100644 src/Azure.DataApiBuilder.Mcp/Telemetry/McpLoggerProvider.cs create mode 100644 src/Core/Telemetry/McpLogLevelConverter.cs create mode 100644 src/Service.Tests/UnitTests/McpLogNotificationTests.cs create mode 100644 src/Service.Tests/UnitTests/McpStdoutWriterTests.cs diff --git a/src/Azure.DataApiBuilder.Mcp/Core/McpStdioServer.cs b/src/Azure.DataApiBuilder.Mcp/Core/McpStdioServer.cs index 0588050fb0..8ec232981a 100644 --- a/src/Azure.DataApiBuilder.Mcp/Core/McpStdioServer.cs +++ b/src/Azure.DataApiBuilder.Mcp/Core/McpStdioServer.cs @@ -8,6 +8,7 @@ using Azure.DataApiBuilder.Core.Configurations; using Azure.DataApiBuilder.Core.Telemetry; using Azure.DataApiBuilder.Mcp.Model; +using Azure.DataApiBuilder.Mcp.Telemetry; using Azure.DataApiBuilder.Mcp.Utils; using Microsoft.AspNetCore.Http; using Microsoft.Extensions.Configuration; @@ -26,6 +27,7 @@ public class McpStdioServer : IMcpStdioServer { private readonly McpToolRegistry _toolRegistry; private readonly IServiceProvider _serviceProvider; + private readonly McpStdoutWriter _stdoutWriter; private readonly string _protocolVersion; private const int MAX_LINE_LENGTH = 1024 * 1024; // 1 MB limit for incoming JSON-RPC requests @@ -35,6 +37,11 @@ public McpStdioServer(McpToolRegistry toolRegistry, IServiceProvider serviceProv _toolRegistry = toolRegistry ?? throw new ArgumentNullException(nameof(toolRegistry)); _serviceProvider = serviceProvider ?? throw new ArgumentNullException(nameof(serviceProvider)); + // Resolve the shared stdout writer so JSON-RPC responses and + // notifications/message frames are serialized through one lock. + // Falls back to a fresh instance if DI didn't register one (defensive). + _stdoutWriter = _serviceProvider.GetService() ?? new McpStdoutWriter(); + // Allow protocol version to be configured via IConfiguration, using centralized defaults.

This causes two problems: - Some logs appear even when LogLevel is set to some value that would impede those logs to appear. - Some logs don't appear at all, even when LogLevel is set to a value that should allow them to be logged. - Closes issue #3256 & #3255 The CLI logger still outputs some logs even when the LogLevel is set to `none`. It is expected that if the LogLevel set is `none` or some other level that shouldn't output the `information` level, the logs will not appear. ## What is this change? Important Note: These changes currently only allow us to change the LogLevel from the CLI with the `default` namespace in the config file. An task was created to solve this issue: https://github.com/Azure/data-api-builder/issues/3451 In order to solve issue #3262: - We removed the LogBuffer from the services inside of `Startup.cs`, this is necessary since we wanted each class to have its own LogBuffer so that we are able to tell from which logger the logs are being outputted. - Then, we also correctly initialized the `Startup` logger by changing the method that it was using to initialize the logger, it now uses `CreateLoggerFactoryForHostedAndNonHostedScenario` which checks if there are any LogLevel namespaces from the config file that can be applicable for the specific logger. It is important to note that there are multiple places where the logs are flushed in order to cover for the cases in which an exception is found and causes DAB to end abruptly, and when we there is an IsLateConfigured scenario. - We also changed the logger for the LogBuffer in all the missing places where it creates logs before the logger is able to properly initialize to add those logs to the LogBuffer and only flush them after the loggers are initialized. In order to solve issue #3256 & #3255: - We changed the CLI so that we add all the logs go to a single global LogBuffer that is created inside the `StartOptions.cs` until it is able to deserialize the RuntimeConfig and find which level to set the `LogLevel` in order to flush all the logs. - This is something that we only want to happen when we use the `dab start` command, which is why we only make this change in the `StartOptions.cs` file, on the function `TryStartEngineWithOptions` inside of `ConfigGenerator.cs`, and a few functions from `Utils.cs` and `ConfigMerger.cs` that are used inside the `TryStartEngine` function. ## How was this tested? - [ ] Integration Tests - [x] Unit Tests ## Sample Request(s) - dab start --LogLevel none - dab start --LogLevel error --------- Co-authored-by: Aniruddh Munde * Update config validation logic for entities (#3306) ## Why make this change? Closes https://github.com/Azure/data-api-builder/issues/3267 ## What is this change? Alters the validation logic in the following way. Is top-level config with data-source-files? (we call this a `Root` config file) ├── YES │ ├── Has datasource? → ValidateEntityPresence (same rules as non-root) │ ├── No datasource but has entities/autoentities? → ERROR │ └── No datasource, no entities → VALID (children provide everything) │ └── For each child → ValidateNonRootConfig(child, filename) │ └── NO (standalone or child config) ├── No datasource? → ERROR: "data source is required" └── Has datasource → ValidateEntityPresence Note: A top-level config file without any children data-source files is NOT considered a root. And an intermediary config file, ie: is a child, that also has child configs is NOT a root. Only a top-level config with children configs is a Root. #### ValidateEntityPresence Count resolved autoentities from AutoentityResolutionCounts total = manual entities + resolved autoentities total == 0? → ERROR: "No entities found" total > 0 but autoentities discovered nothing? → WARN: "Autoentities configured but none discovered" No double messaging. If total is 0, only the error is recorded, not the warning. ## How was this tested? ### Truth table — top-level config Variables (`1` = present / non-empty, `0` = absent / empty): - **DSF** — `data-source-files` present - **DS** — `data-source` present - **E** — manual `entities` count > 0 - **AE** — `autoentities` count > 0 (presence, *not* resolved count) Path is determined by `IsRootConfig = (DSF == 1) && !IsChildConfig`. | #

Enables MCP clients (like MCP Inspector, Claude Desktop, VS Code Copilot) to receive real-time log output via MCP `notifications/message`. Related: #3274 (depends on PR #3419) ## What is this change? When `logging/setLevel` is called with a level other than "none", logs are sent to MCP clients as JSON-RPC notifications: ```json { "jsonrpc": "2.0", "method": "notifications/message", "params": { "level": "info", "logger": "Azure.DataApiBuilder.Service.Startup", "data": "Starting Data API builder..." } } ``` ### New files: - `McpLogNotificationWriter.cs` - Writes logs as MCP notifications to stdout - `McpLogger.cs` / `McpLoggerProvider.cs` - ILogger implementation for .NET logging pipeline - `McpLogNotificationTests.cs` - Unit tests (8 tests) ### Modified files: - `Program.cs` - Registers `McpNotificationWriter` and `McpLoggerProvider` for MCP mode - `McpStdioServer.cs` - Enables notifications when `logging/setLevel` is called ## How was this tested? - Unit tests: 6 tests covering level mapping, enable/disable, JSON format - Manual testing with MCP Inspector: verified notifications appear when `logging/setLevel` is sent ## Note This PR targets `dev/anushakolan/set-log-level` (PR #3419) as it depends on the `logging/setLevel` implementation. * Fix OData filter format in JWT string claims (#3510) ## Why make this change? Fixes the format of the OData filter in JWT string claims. ## What is this change? In `AuthorizationResolver` we now escape embedded single quotes in claim values by doubling them, before we wrap the value in single quotes for OData substitution. This conforms to the OData 4.01 ABNF rule for string literals (Section 7: Literal Data Values). Policy: `@item.col1 eq @claims.userId` Claim `userId` value: `alice' or 1 eq 1 or '` | | Resulting OData predicate | | --- | --- | | Before | `col1 eq 'alice' or 1 eq 1 or ''` <- injects `or 1 eq 1`, bypassing row-level auth | | After | `col1 eq 'alice'' or 1 eq 1 or '''` <- attacker payload contained inside a single string literal | ## How was this tested? New parameterized test `DbPolicy_StringClaim_SingleQuotesEscaped_PreventsODataInjection` in `src/Service.Tests/Authorization/AuthorizationResolverUnitTests.cs` covers: - Active OR-predicate injection attempt is neutralized. - Legitimate apostrophe-bearing value (e.g. `O'Brien`) is safely escaped. - Value composed solely of single quotes is fully escaped. - Value with no single quotes is unchanged aside from the enclosing quotes (no regression). ## Sample Request(s) ```json { "entities": { "Note": { "source": "dbo.Notes", "permissions": [ { "role": "authenticated", "actions": [ { "action": "read", "policy": { "database": "@item.ownerId eq @claims.userId" } } ] } ] } } } ``` Reproduction - `userId` claim value of `alice' or 1 eq 1 or '`: ```http GET /api/Note HTTP/1.1 Authorization: Bearer X-MS-API-ROLE: authenticated ``` - Before fix: the engine emitted `WHERE ownerId = 'alice' or 1 eq 1 or ''`, returning rows owned by other users. - After fix: the engine emits `WHERE ownerId = 'alice'' or 1 eq 1 or '''`, which compares against the literal string `alice' or 1 eq 1 or '` and returns no unauthorized rows.
