 - **Semantic Search**: Converting a natural language query into a vector to
  perform similarity searches.

+## Hidden Parameter Duplication (valueFromParam)
+
+When building tools for vector ingestion, you often need the same input string
+twice:
+
+1. To store the original text in a TEXT column.
+1. To generate the vector embedding for a VECTOR column.
+
+Requesting an Agent (LLM) to output the exact same string twice is inefficient
+and error-prone. The `valueFromParam` field solves this by allowing a parameter
+to inherit its value from another parameter in the same tool.
+
+### Key Behaviors
+
+1. Hidden from Manifest: Parameters with valueFromParam set are excluded from
+   the tool definition sent to the Agent. The Agent does not know this parameter
+   exists.
+1. Auto-Filled: When the tool is executed, the Toolbox automatically copies the
+   value from the referenced parameter before processing embeddings.
+
 ## Example

 The following configuration defines an embedding model and applies it to
 specific tool parameters.

mahlevanshika	1d7c498116	fix(dataplex): Capture GCP HTTP errors in MCP Toolbox (#2347 ) ### Description fix: Surface Dataplex API errors in MCP results This change addresses issue https://github.com/googleapis/genai-toolbox/issues/2203, where Dataplex API errors, such as '403 Forbidden' (Permission Denied), were not being properly surfaced in the MCP tool results. Previously, these critical API errors would manifest as generic "connection interrupted" messages, significantly hindering developer debugging and trust in the Toolbox. The fix enhances the error handling within the 'dataplexsearchentries' and 'dataplexsearchaspecttypes' tools. When an error occurs during the iteration of Dataplex API results, the system now: Utilizes 'google.golang.org/grpc/status.FromError' to attempt to convert the returned error into a gRPC status. This is crucial because Google Cloud client libraries often return errors compatible with gRPC. If the error is a gRPC status, the canonical error code (e.g., 'codes.PermissionDenied') and the associated error message are extracted. This ensures that users receive clear actionable error feedback, allowing for quicker diagnosis and resolution of issues like missing IAM permissions. This aligns with best practices for API error surfacing, improving the usability and reliability of the Dataplex tools within the GenAI Toolbox. Fixes https://github.com/googleapis/genai-toolbox/issues/2203 ## PR Checklist > Thank you for opening a Pull Request! Before submitting your PR, there are a > few things you can do to make sure it goes smoothly: - [ ] Make sure you reviewed [CONTRIBUTING.md](https://github.com/googleapis/genai-toolbox/blob/main/CONTRIBUTING.md) - [ ] Make sure to open an issue as a [bug/issue](https://github.com/googleapis/genai-toolbox/issues/new/choose) before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea - [ ] Ensure the tests and linter pass - [ ] Code coverage does not decrease (if any source code was changed) - [ ] Appropriate docs were updated (if necessary) - [ ] Make sure to add `!` if this involve a breaking change 🛠️ Fixes #<issue_number_goes_here> --------- Co-authored-by: Wenxin Du <117315983+duwenxin99@users.noreply.github.com> Co-authored-by: Averi Kitsch <akitsch@google.com>	2026-01-23 19:53:59 +00:00

dishaprakash	e535b372ea	feat: Support combining multiple prebuilt configurations (#2295 ) ## Description This PR introduces support for merging multiple prebuilt configurations. To ensure compatibility, the following restrictions apply: - No Naming Collisions: Configurations cannot share duplicate names for any resources (Tools, Sources, Toolsets, Auth Services, etc.). - Shared Environment Variables: If multiple sources rely on the same environment variable, they must share the same value; unique values for the same variable are not supported ## Usage Examples ### Successful Initialization You can load multiple prebuilt configurations by either repeating the --prebuilt flag or by providing a comma-separated list. Option 1: Multiple Flags ``` ./toolbox --prebuilt alloydb-postgres --prebuilt alloydb-postgres-admin ``` Option 2: Comma-Separated Values ``` ./toolbox --prebuilt alloydb-postgres,alloydb-postgres-admin ``` ### Initialization Failure (Resource Conflict) If two or more configurations define a resource with the same name (such as a Tool or Source, etc.), the server will fail to start and display a conflict error. ``` ./toolbox --prebuilt alloydb-postgres --prebuilt cloud-sql-mysql 2026-01-13T11:14:50.758121799Z INFO "Using prebuilt tool configurations for: alloydb-postgres, cloud-sql-mysql" 2026-01-13T11:14:50.764578167Z ERROR "resource conflicts detected:\n - tool 'execute_sql' (file #2)\n - tool 'list_active_queries' (file #2)\n - tool 'get_query_plan' (file #2)\n - tool 'list_tables' (file #2)\n\nPlease ensure each source, authService, tool, toolset and prompt has a unique name across all files" ``` ## PR Checklist > Thank you for opening a Pull Request! Before submitting your PR, there are a > few things you can do to make sure it goes smoothly: - [x] Make sure you reviewed [CONTRIBUTING.md](https://github.com/googleapis/genai-toolbox/blob/main/CONTRIBUTING.md) - [x] Make sure to open an issue as a [bug/issue](https://github.com/googleapis/genai-toolbox/issues/new/choose) before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea - [x] Ensure the tests and linter pass - [x] Code coverage does not decrease (if any source code was changed) - [x] Appropriate docs were updated (if necessary) - [x] Make sure to add `!` if this involve a breaking change 🛠️ Fixes #1855 --------- Co-authored-by: Averi Kitsch <akitsch@google.com>	2026-01-22 23:00:17 +00:00
Yuan Teoh	5054212fa4	feat!: validate tool naming (#2305 ) Check for naming validation for Tool. This validation follows the MCP SEP986 [naming guidance](`1b1eb60ec4/docs/specification/draft/server/tools.mdx (tool-names)`). Name will be checked before MCP initialization (where specs version is confirmed). Hence, we will be implementing this across all versions and endpoints. This will be a breaking change for user that currently uses other special character as name (other than `_`, `-`, `.`)	2026-01-22 21:52:37 +00:00

Wenxin Du	15101b1edb	feat(tools): Add `valueFromParam` support to Tool config (#2333 ) This PR introduces a new configuration field valueFromParam to the tool definitions. This feature allows a parameter to automatically inherit its value from another sibling parameter, mainly to streamline the configuration of vector insertion tools. Parameters utilizing valueFromParam are excluded from the Tool and MCP manifests. This means the LLM does not see these parameters and is not required to generate them. The value is resolved internally by the Toolbox during execution.	2026-01-21 16:35:27 -08:00
