01 · Install Perigon

before you install - you'll need

PERIGON_API_KEY is optional or environment-specific per the README.

Claude Code

claude mcp add goperigon-perigon-mcp-server --transport http https://mcp.perigon.io/v1/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "goperigon-perigon-mcp-server": {
      "url": "https://mcp.perigon.io/v1/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as remote - your agent's requests go to mcp.perigon.io

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license Apache-2.0 - declared in the repository

registry namespace io.github.goperigon is GitHub-verified and matches the repo owner
