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`.
This feature includes the following:
* Implement initialize lifecycle (including version negotiation)
* Add the v20250326 schema
* Supporting the `DELETE` and `GET` endpoint for MCP.
* Supporting streamable HTTP (without SSE).
* Terminating sessions after timeout (default = 10 minutes from last
active).
* Toolbox do not support batch request. Will response with `Invalid
requests` if batch requests is received.
User agent will be set as "genai-toolbox/" + versionString.
Instead of a panic, Toolbox will throw an error if the source fail to
retrieve `user agent`.
This will also be consistent with setting and getting logger from
context.
Rename existing `authSource` to `authService` through deprecation.
`AuthService` more clearly distinguishes it from `Sources` objects.
`authSources` will be converted into `authServices` after the
unmarshalling process. A warning log is shown if `authSources` are used
(for both within tools parameters and defining auth services):
```
2025-02-20T13:57:51.156025-08:00 WARN "`authSources` is deprecated, use `authServices` for parameters instead"
2025-02-20T13:57:51.156569-08:00 WARN "`authSources` is deprecated, use `authServices` instead"
2025-02-20T13:57:52.047584-08:00 INFO "Initialized 1 sources."
...
```
The manifest generated will continue to use `authSources` to keep
compatibility with the sdks:
```
{
"serverVersion":"0.1.0",
"tools":{
"test_tool2":{
"description":"Use this tool to test\n",
"parameters":[{
"name":"user_id",
"type":"string",
"description":"Auto-populated from Google login",
"authSources":["my-google-auth"]
}]
}
}
}
```
Test cases with `authSources` are kept for compatibility. Will be
removed when `authSources` are no longer supported.
Add user agent to cloud databases that provides us anonymized data
request count, number of users, number of projects, and other
environment settings.
User agent is using the format: `genai-toolbox/$version+metadata`
Add debug logs to Toolbox.
For example when a http fail, it will just show Error at the http level,
but not log with actual error message. err message are returned to the
api as following `{"status":"Internal Server Error","error":"error while
invoking tool: unable to execute client: spanner: code =
\"InvalidArgument\", desc = \"invalid session pool\""}`.
After adding this, if user/dev run toolbox with `--log-level=debug`, it
will output the following (debug log in addition to the error for http
request):
```
2025-01-08T14:16:25.040824-08:00 DEBUG "error while invoking tool: unable to execute client: spanner: code = \"InvalidArgument\", desc = \"invalid session pool\""
2025-01-08T14:16:25.040968-08:00 ERROR Response: 500 Server Error service: "httplog" httpRequest: {url: "http://127.0.0.1:5000/api/tool/test_tool_two/invoke" method: "POST" path: "/api/tool/test_tool_two/invoke" remoteIP: "127.0.0.1:51708" proto: "HTTP/1.1" requestID: "yuanteoh-macbookpro.roam.internal/N7LNMcLIUH-000001" scheme: "http" header: {user-agent: "curl/8.7.1" accept: "*/*" content-type: "application/json" content-length: "2"}} httpResponse: {status: 500 bytes: 167 elapsed: 0.301917}
```
Adds logic to make the server shutdown gracefully, including better
respecting cancelled contexts and providing up to 10 seconds to finish
current connections.
1. Add []ParamAuthSource to every Parameter type implementation to
support authenticated configs. Create new constructors for types with
auth.
2. Tool invocation API changes to parse auth header and authentecated
parameters.
3. Add authSources to Tool manifest.
End to end integration test for cloudsql postgres.
Include checks for one tool's get (manifest) and post (invoke) endpoint.
Integration tests are excluded from regular unit tests.
Logging support 4 different types of logging (debug, info, warn, error).
The default logging level is Info.
User will be able to set flag for log level (allowed values: "debug",
"info", "warn", "error"), example:
`go run . --log-level debug`
User will be able to set flag for logging format (allowed values:
"standard", "JSON"), example:
`go run . --logging-format json`

Moves all of the "source" and "tool" implementations into their own
packages. This layout makes it a bit more clear where the
implementations are, and seems likely to scale more cleanly as more
sources and tools are added.
1. Calculate tool manifests when server starts.
2. Add toolset manifest endpoints.

Add `Toolset` implementation to the `tools` package:
- struct and configs.
- Custom `UnmarshalYAML` function.
- Initialization function that validates if tools specified for the
toolset exist.
