The Matra rich text editor's documentation as an MCP server: every extension, command and API.

Matra MCP Server (com.matrajs/matra)

The Matra rich text editor documentation is exposed as a Model Context Protocol (MCP) server, so AI tools can read it. The server is described as having zero dependencies. It can run over stdio (intended for desktop clients) or over HTTP on http://localhost:3333/mcp, using npx -y @matrajs/mcp.

🛠️ Key Features

Matra documentation as an MCP server
“Every extension, command and API” covered by the documentation
Zero dependencies

🚀 Use Cases

Connect an MCP-enabled client to Matra’s documentation
Use stdio transport via npx -y @matrajs/mcp
Use HTTP transport via npx -y @matrajs/mcp --http

⚡ Developer Benefits

Documentation available to AI tools through MCP
Supports typical MCP client setup flows (e.g., adding the server by command or config)

⚠️ Limitations

Documentation excerpt does not specify tool availability, method names, or any behavior beyond running and exposing the documentation.

@matrajs/mcp

The Matra documentation as a Model Context Protocol server, so any AI tool can read it. Zero dependencies, like every other Matra package.

npx -y @matrajs/mcp            # stdio · what a desktop client spawns
npx -y @matrajs/mcp --http     # http://localhost:3333/mcp

Connect it, step by step

Claude Code

claude mcp add matra -- npx -y @matrajs/mcp

Claude Desktop — in claude_desktop_config.json:

json

{
  "mcpServers": {
    "matra": { "command": "npx", "args": ["-y", "@matrajs/mcp"] }
  }
}

Cursor — in .cursor/mcp.json, the same object under "mcpServers".

Codex — in ~/.codex/config.toml:

toml

[mcp_servers.matra]
command = "npx"
args = ["-y", "@matrajs/mcp"]

Anything that speaks HTTP — run npx -y @matrajs/mcp --http 3333 and point the client at http://localhost:3333/mcp.

Then ask the tool something about Matra. It will call search_docs, read the page it needs, and answer from the documentation rather than from memory.

What it serves

Tool	Does
`list_docs`	Every page, with its slug and a one-line description.
`read_doc { slug }`	One page, as Markdown.
`search_docs { query, limit? }`	Ranked pages with a snippet each.

Every page is also a resource at matra://docs/<slug>.

The pages are the repository's Markdown — README, the engine notes, benchmarks, security, the changelog — and every page of matrajs.com/docs, converted to Markdown at build time and shipped inside the package. Nothing is fetched at runtime.

Use it from code

import { createServer } from '@matrajs/mcp'

const server = createServer(docs)
server.handle({ jsonrpc: '2.0', id: 1, method: 'tools/list' })

createServer is the protocol without a transport: one message in, one reply out. Put it behind whatever transport you already have.
