Description

Adds NewInProcessClientWithOptions, a single in-process client constructor that accepts the existing ClientOption API and wires sampling, elicitation, and roots handlers into the in-process transport. Existing specialized constructors remain unchanged for compatibility.

Type of Change

  • Bug fix (non-breaking change that fixes an issue)
  • New feature (non-breaking change that adds functionality)
  • MCP spec compatibility implementation
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • Documentation update
  • Code refactoring (no functional changes)
  • Performance improvement
  • Tests only (no functional changes)
  • Other (please describe):

Checklist

  • My code follows the code style of this project
  • I have performed a self-review of my own code
  • I have added tests that prove my fix is effective or that my feature works
  • I have updated the documentation accordingly

Additional Information

This is intentionally a thin composition layer over the existing transport.InProcessOption hooks. It makes embedded Agent, sandbox, and multi-handler test setups use the same public client options as network clients, without changing the transport contract or removing the existing sampling constructor.

The regression test exercises one real in-process tool that requests sampling, elicitation, and roots in the same call, and verifies a normal client option is preserved as well.

Validation:

go test ./... -race
go vet ./...
(cd otel && go test ./... -race && go vet ./...)

All commands passed locally.

Summary by CodeRabbit

  • New Features
    • Added support for configuring in-process clients with client options.
    • Added host handlers for sampling, elicitation, and roots interactions.
    • Added support for limiting input round trips during client operations.
  • Tests
    • Added coverage verifying configured options and host handler behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 10523

The change adds a new in-process client composition path with regression coverage, but merge readiness is incomplete until the repository’s required lint and code-generation checks are run and any generated updates are committed.
