Toolrails is built on two open-source packages. They work with any MCP tool list, on Node, Deno, Bun and edge runtimes, with no Toolrails account.

Tool searchv0.4.2

@toolrails/tool-search

Give it any list of tools and a request. It returns the few tools that matter and what they depend on.

terminal

npm i @toolrails/tool-search

search.ts

import { createIndex } from '@toolrails/tool-search'

const index = await createIndex(tools, { enrich: true })
const hits = await index.search('list open tickets', {
  filter: { read_only: true },
  limit: 5,
})
