Matt Van Horn 15781bfcc0 feat(mcp): scaffold Go module under mcp/ for Claude Desktop bundle
Add a new top-level mcp/ Go module that will host the Claude Desktop MCPB
server. U1 of the Claude Desktop .mcpb bundle plan: scaffold only, no
behavior yet.

- mcp/go.mod targets Go 1.22+ with mark3labs/mcp-go as the planned
  dependency (added in U3 when the server wiring lands).
- mcp/scripts/sync-engine.sh mirrors skills/last30days/scripts/ into
  mcp/vendored/ before each build, keeping the Code skill and Desktop
  bundle on the same engine source.
- Root .gitignore excludes mcp/vendored/ and mcp/build/ so the engine
  mirror and cross-compiled binaries stay local.

last30days-pp-mcp

Go MCP server that wraps the last30days Python engine for Claude Desktop. Packaged as a .mcpb bundle (drag-drop install into Claude Desktop).

The MCP server exposes a single research tool that mirrors the /last30days <topic> slash command available in Claude Code. At runtime the binary extracts the vendored Python engine into a per-user cache and shells out to python3 to produce the synthesis input Claude renders.

Architecture

  • cmd/last30days-pp-mcp/ - server entry point
  • internal/engine/ - embed.FS of the Python engine + cache extractor + subprocess wrapper
  • internal/tools/ - MCP tool handlers (currently research)
  • vendored/ - mirror of skills/last30days/scripts/, generated by scripts/sync-engine.sh (gitignored)
  • manifest.json - MCPB v0.3 manifest consumed by Claude Desktop and printing-press bundle

Local build

# Mirror the Python engine into vendored/.
bash scripts/sync-engine.sh

# Build for the current host.
go build -ldflags "-X main.Version=dev" -o build/last30days-pp-mcp ./cmd/last30days-pp-mcp

# Package as a .mcpb (requires the printing-press binary on PATH).
printing-press bundle . --skip-build --binary build/last30days-pp-mcp

The output .mcpb lands at build/last30days-pp-mcp-<os>-<arch>.mcpb. Drag it into Claude Desktop's Extensions panel to install.

Runtime requirements

End users need Python 3.12+ on PATH. The bundle ships the engine source but relies on the host interpreter.

Versioning

The MCPB manifest.json version is hand-bumped in the same PR that ships engine changes worth releasing. Release CI stamps the Go binary's main.Version from the tag.
