Wire read-only MCP server for coding agents (v0.1.2)#19
Merged
Conversation
dtc mcp start now runs a real MCP server over stdio, exposing the three implemented read-only tools (list_concepts, explain_concept, get_context_pack) so coding agents can query local evidence-backed repository memory. - MCP SDK is an optional extra: pip install "devtime-ei[mcp]" (core stays lean) - stdout is reserved for the JSON-RPC stream; diagnostics go to stderr - read-only surface only: no write tools, no network listener, no source code - tools return a clear not_initialized error outside a scanned repo - mcp preview separates implemented tools from planned ones (no overclaiming) - README gains a "Use with coding agents (MCP)" section with Claude Code and .mcp.json setup; LIMITATIONS/ROADMAP updated to stop saying "not wired" - version 0.1.2, release notes added, 104 tests (7 new), end-to-end verified with the official MCP Python client against a wheel install
Adds server.json (io.github.shakargy/devtime, pypi package devtime-ei, stdio) and a manual workflow that publishes it to the official MCP Registry using GitHub OIDC (no stored secrets). The mcp-name ownership marker is embedded in the README so the registry can validate the PyPI package.
