Production Master

---

The standard MCP server for the Production Master hosted incident-investigation service — connect any MCP client and drive investigations as tool calls.

production-master-mcp speaks the Model Context Protocol. It exposes the Production Master tool set to any MCP-capable client — Claude Code, Cursor, Codex, OpenCode, or anything else that speaks MCP — and relays each tool call to the hosted service. The intelligence runs on the service; this server is the protocol front door in front of it.

Authentication is pass-through: the client supplies an Authorization: Bearer <token> header, the server forwards it opaquely to the hosted service, and it stores no credentials of its own. Tool input/output schemas come from the shared npm package @production-master/mcp-tool-contract (publication pending), so every client sees the same, versioned tool surface.

Features

• Standard MCP, any client — one server, reachable from Claude Code, Cursor, Codex, OpenCode, or any MCP-capable client. No per-editor fork.
• Two transports — Streamable HTTP (POST /mcp) for hosted/remote use, and stdio for running locally next to your client.
• Pass-through auth — the caller's bearer token is forwarded opaquely upstream and never stored, logged, or persisted by the server.
• Contract-driven tools — tool schemas are published in @production-master/mcp-tool-contract, keeping the tool surface stable and versioned across clients.

Prerequisites

• Node.js 22 (see .nvmrc once packages land)
• Access to the Production Master hosted service — the server forwards your bearer token to it; you supply that token from your MCP client.
• An MCP-capable client: Claude Code, Cursor, Codex, OpenCode, or any client speaking MCP.

Quick Start

Status: the server packages under packages/ are being populated via PRs. The connection patterns below describe how a client registers an MCP server over each transport; the concrete package name and endpoint land with those PRs. See CHANGELOG.

Every client connects the same two ways, matching the two transports: point it at the server's HTTP endpoint (<server-url>/mcp) with an Authorization: Bearer <token> header, or run the server locally over stdio (npx -y @production-master/mcp).

Claude Code

# HTTP
claude mcp add --transport http production-master <server-url>/mcp \
  --header "Authorization: Bearer <your-token>"

# or stdio (local)
claude mcp add production-master -- npx -y @production-master/mcp

Cursor

Register the server in .cursor/mcp.json:

{
  "mcpServers": {
    "production-master": {
      "url": "<server-url>/mcp",
      "headers": { "Authorization": "Bearer <your-token>" }
    }
  }
}

Codex

Register the server in .codex/config.toml (stdio):

[mcp_servers.production-master]
command = "npx"
args = ["-y", "@production-master/mcp"]

OpenCode / other MCP clients

Any MCP-capable client works: give it the <server-url>/mcp HTTP endpoint plus the bearer header, or a stdio server entry launching npx -y @production-master/mcp. Full walkthrough: docs/user/quick-start.md.

Architecture

The server is a thin protocol boundary: it terminates MCP, forwards tool calls to the hosted service, and streams results back. It holds no investigation logic and no stored credentials.

Three concerns live here: transport (Streamable HTTP POST /mcp and stdio), auth pass-through (forward the caller's bearer token upstream, store nothing), and tool routing (validate against the schemas from @production-master/mcp-tool-contract and relay to the service).
