feat(agent-mcp): Model Context Protocol server over stdio - #1482
Merged
Conversation
Expose the built-in agent tools (builtinTools over an AgentWorkspace) as an MCP server: io.modelcontextprotocol 2.0.0, tools/resources/prompts, the permission gate routed on the wire, and a standalone stdio entry point (--project / --auto-accept) backed by FileSystemAgentWorkspace. Add GitHub workflows for the MCP module tests (mcp.yml) and the installable debug APK (apk.yml).

Purely additive :agent-mcp module; verified all agent-api/agent-impl API bindings match main and the MCP SDK 2.0.0 dependency is the official artifact. Approving; releasing CI to confirm the build + tests are green.

Thanks @sankarru — this is a clean, well-scoped contribution. The module is purely additive (nothing in the existing shells depends on it), the agent-api/agent-impl bindings all line up, and CI is green across the board: agent-mcp tests + distribution, the framework suite under CI_CORE_ONLY, and the debug APK build. Nice touch using in-process pipe streams to exercise the full stdio JSON-RPC wire path without spawning a subprocess. Merging now. |

Adds the MCP server module (:agent-mcp) exposing the built-in agent tools over stdio JSON-RPC (io.modelcontextprotocol 2.0.0), plus two CI workflows: mcp.yml (module tests) and apk.yml (installable debug APK). Verified locally: 11/11 agent-mcp tests pass and the stdio binary serves initialize/tools/resources/prompts.
