@ashlrai/locus-mcp

MCP multiplexor for Locus — tools hard-scoped to the active pin so agents cannot act in the wrong tenant.

Install

npm install -g @ashlrai/locus-mcp
# or run via npx after pinning with locus:
npx @ashlrai/locus-mcp

On first run the wrapper downloads the release binary into ~/.locus/bin, or falls back to:

cargo install --git https://github.com/ashlrai/locus --package locus-mcp --locked

Setup (Claude Code / Cursor)

# Install CLI + MCP
npm install -g locus-cli @ashlrai/locus-mcp
# or: cargo install --git https://github.com/ashlrai/locus --package locus-cli --package locus-mcp

locus pin acme
locus setup --client claude   # writes/merges .mcp.json
# restart Claude Code
