This pull request adds support and documentation for connecting Neo4j
databases using the Model Context Protocol (MCP) and the MCP Toolbox. It
introduces a new prebuilt configuration for Neo4j, updates documentation
to guide users through setup across multiple IDEs, and adds tests to
ensure the new configuration is loaded correctly.
**Neo4j MCP Integration:**
* Added a new prebuilt configuration file `neo4j.yaml` defining
`execute_cypher` and `schema` tools for Neo4j, with support for
environment-based configuration.
* Updated the documentation (`neo4j_mcp.md`) with step-by-step
instructions for connecting Neo4j to various IDEs (e.g., VS Code,
Cursor, Claude, Gemini) using MCP Toolbox.
* Expanded the reference documentation to include Neo4j, detailing
required environment variables, permissions, and available tools.
**Testing and Codebase Updates:**
* Updated test cases in `prebuiltconfigs_test.go` to include Neo4j in
the list of expected tool sources and verify the Neo4j configuration can
be fetched and loaded.

This PR introduces ClickHouse support by finishing off
https://github.com/googleapis/genai-toolbox/pull/713. We have had quite
a few requests internally and externally of people who want ClickHouse
support and wish to contribute but can't use the toolbox because of this
stalled PR. We also tried to reach out to @sidpan1 ourselves with no
success so we are going to assume the contributor doesn't have time to
complete. We would like to thank @sidpan1 for getting this going -
community contributions help make ClickHouse better for everyone.
This PR introduces
- Adds ClickHouse HTTPS and HTTP source support (drops native support
and compression in connection)
- Adds tools: `execute_sql`, ~~`describe_table`, `list_databases`,
`list_tables`~~
- Adds unit and integration tests
- Adds docs
Other contributors can build on this foundation

1. Add ask-data-insights tool based on conversational analytic API.
2. Add tokenSource for ask-data-insights tool, it uses access token
instead of client or restService.
3. Add a max row count to source, currently fixed to 50 and used only
for ask-data-insights tool. Later we may make it available for user to
make change and apply to bigquery-execute-sql and bigquery-sql to avoid
return too many data by accident.

## Description
This Pull Request introduces support for the Firebird database as a new
`source` and adds the `firebird-sql` and `firebird-execute-sql` tools.
The implementation follows the architectural pattern established by the
existing PostgreSQL and MySQL tools.
Comprehensive integration tests have been added in the `tests/firebird`
directory, covering table creation, data insertion, and the invocation
of all related tools. Corresponding user and developer documentation has
also been included.
## Test Results
The core functionality is working as demonstrated by the vast majority
of tests passing. However, a few tests fail due to limitations and
inflexibilities in the generic test harness (`tests/tool.go`), which is
not fully compatible with Firebird's specific syntax and behavior.
### Known and Justified Failures:
* **`invoke_my-tool` / `invoke_my-array-tool`:** The `RunToolInvokeTest`
function reuses the same `want` variable for both sub-tests, which have
different inputs and expected outputs. The test is configured for
`my-tool` to pass, which consequently causes the `my-array-tool` test to
fail its assertion. The `got` log for the array test confirms that the
tool returns the correct response for the given input.
* **`invoke_my-exec-sql-tool`:** This test fails because the harness
sends the query `SELECT 1`, which is invalid syntax in Firebird.
Subsequent tests for this tool using DDL and DML (`create`, `select`,
`drop`) all pass, confirming its core functionality.
* **`invoke_select-fields-templateParams-tool`:** This test fails due to
a case-sensitivity mismatch in column names (`NAME` vs. `name`). The
expected output in the test harness is hardcoded with a lowercase name.
* **Authentication Tests:** All authentication-related tests are
failing. This appears to be a general issue with the local test
environment setup and is not specific to the Firebird implementation.
## Next Steps
I believe the implementation is ready for review. I am available to make
any requested changes.
Feat #935

## Add firestore-update-document tool
Adds a new tool for updating existing documents in Firestore
collections.
__What it does:__
- Updates documents at any path in Firestore
- Supports partial updates with field masks for selective field
modification
- Handles all Firestore data types (strings, numbers, booleans,
timestamps, geopoints, arrays, maps, etc.)
- Supports field deletion using updateMask
- Uses Firestore's native JSON format for type safety
- Can update nested fields within maps using dot notation
__Key parameters:__
- `documentPath`: The path of the document to update
- `documentData`: The document content in Firestore JSON format
- `updateMask`: Optional array of field paths for selective updates
- `returnData`: Optional flag to include updated document in response
__Special features:__
- When `updateMask` is provided, only specified fields are updated
- Can access nested fields with dot notation (e.g., 'address.city',
'user.profile.name')
- Without updateMask, performs a merge operation updating all provided
fields
Introduces a new Hugo shortcode, `includeRegion`, to allow embedding
specific, tagged regions from source files directly into Markdown
content.
This helps maintain a single source of truth for code snippets and other
repeated content, such as setup instructions, preventing duplication and
simplifying updates across multiple quickstart guides.

## Description
Users deploying Toolbox to Cloud Run for the first time can encounter
common friction points that are not covered in the current
documentation. This can lead to deployment failures and a frustrating
setup experience, particularly around container port configuration and
IAM permissions.
