This PR introduces a significant update to the Toolbox configuration
file format, which is one of the primary **breaking changes** required
for the implementation of the Advanced Control Plane.
# Summary of Changes
The configuration schema has been updated to enforce resource isolation
and facilitate atomic, incremental updates.
* Resource Isolation: Resource definitions are now separated into
individual blocks, using a distinct structure for each resource type
(Source, Tool, Toolset, etc.). This improves readability, management,
and auditing of configuration files.
* Field Name Modification: Internal field names have been modified to
align with declarative methodologies. Specifically, the configuration
now separates kind (general resource type, e.g., Source) from type
(specific implementation, e.g., Postgres).
# User Impact
Existing tools.yaml configuration files are now in an outdated format.
Users must eventually update their files to the new YAML format.
# Mitigation & Compatibility
Backward compatibility is maintained during this transition to ensure no
immediate user action is required for existing files.
* Immediate Backward Compatibility: The source code includes a
pre-processing layer that automatically detects outdated configuration
files (v1 format) and converts them to the new v2 format under the hood.
* [COMING SOON] Migration Support: The new toolbox migrate subcommand
will be introduced to allow users to automatically convert their old
configuration files to the latest format.
# Example
Example for config file v2:
```
kind: sources
name: my-pg-instance
type: cloud-sql-postgres
project: my-project
region: my-region
instance: my-instance
database: my_db
user: my_user
password: my_pass
---
kind: authServices
name: my-google-auth
type: google
clientId: testing-id
---
kind: tools
name: example_tool
type: postgres-sql
source: my-pg-instance
description: some description
statement: SELECT * FROM SQL_STATEMENT;
parameters:
- name: country
type: string
description: some description
---
kind: tools
name: example_tool_2
type: postgres-sql
source: my-pg-instance
description: returning the number one
statement: SELECT 1;
---
kind: toolsets
name: example_toolset
tools:
- example_tool
```

[Cassandra](https://cassandra.apache.org/_/cassandra-basics.html) is a
NoSQL distributed database. By design, NoSQL databases are lightweight,
open-source, non-relational, and largely distributed. Counted among
their strengths are horizontal scalability, distributed architectures,
and a flexible approach to schema definition.

This PR
- adds a new source for cassandra
- adds a new tool _cassandra-cql_ with support for executing predefined
parameterized CQL queries on cassandra
- adds unit and integration tests for the tool and the source
- adds documentation for the cassandra source and cassandra-cql tool

Existing `/mcp` endpoint of Toolbox does not support auth (authorized
invocation and authenticated parameters). This PR add support for
Toolbox auth to the `/mcp` endpoint.
Added integration test for MCP with auth.
Note that Toolbox auth is **NOT** supported in stdio transport protocol,
invocations of tools with auth will result in error.
Add options for `RunToolInvokeTest()`, `RunMCPToolCallMethod()`,
`RunExecuteSqlToolInvokeTest()`.
When I was trying to update integration test for Firebird. They have a
different syntax from the usual `SELECT 1` that the other DBs are using.
If we want to update the `SELECT 1` statement in the test cases, we will
have to add a new argument and update all the other integration tests.
With `Options`, we can just add customization without having the need to
update all other integration tests. This allow the integration tests to
be more flexible. With this, we can also remove the
`GetNonSpannerWant()` since those can be set as default values for the
`Options`.
- Spanner: convert array to typed before querying, as Spanner does not
accept non-typed array []any
- BigQuery: fix https://github.com/googleapis/genai-toolbox/issues/793
- Bigtable: add the required `ElemType` for array-type params
- Redis/Valkey: change indexing to append to avoid extra spaces
Add integration tests for array parameters, skipped for the sources not
supporting arrays:
- SQLite
- Cloud SQL MSSQL
- Cloud SQL MySQL
- MSSQL
- MySQL
Allow Toolbox server to automatically update when users modify their
tool configuration file(s), instead of requiring a restart.
This feature is automatically enabled, but can be turned off with the
flag `--disable-reload`.
