praetor-mcp (npm wrapper)

Delivers the pure-Rust praetor MCP server binary via npm, so it can be run with npx like any other MCP server:

{ "mcpServers": { "praetor": {
  "command": "npx",
  "args": ["-y", "praetor-mcp"],
  "env": {
    "PRAETOR_KEY": "…", "PRAETOR_PEERS": "…",
    "PRAETOR_URL": "http://127.0.0.1:9440", "PRAETOR_AGENT_DB": "…"
  }
} } }

There is no JavaScript reimplementation — this is a native binary distributed through npm (the same pattern as esbuild, Biome, and SWC). On install, a postinstall step downloads the prebuilt static binary for your platform from the matching GitHub Release; the bin shim then execs it.

Prefer not to use npm? cargo install --git https://github.com/wilfreddenton/praetor gives you the same binary.

Releasing (maintainer notes)

The npm version and the git tag must match — the postinstall downloads assets from releases/download/v<version>/:

1. Bump the crate version (Cargo.toml) and this package.json in lockstep.
2. git tag v<version> && git push --tags → release.yml builds every target and attaches praetor-mcp-<target> assets to the release.
3. Once the release assets exist: cd npm && npm publish.
