Easiest — one line, then restart. (Or just tell Claude Code: “add the Pipeworx MCP server at https://gateway.pipeworx.io/oauth/mcp” and it runs this for you.) Then run /mcp and authenticate: free, and it takes you from 50 calls a day to 200.

claude mcp add --transport http pipeworx https://gateway.pipeworx.io/oauth/mcp

Or install the plugin — same tools, plus an auto-routing skill so Claude reaches for ask_pipeworx without being told:

/plugin marketplace add pipeworx-io/claude-code-plugin
/plugin install pipeworx

1. Open claude.ai/customize/connectors.
2. Click Add custom connector.
3. Name it Pipeworx, paste the first URL below, and save. Leave the OAuth client ID/secret blank — the connector registers itself.
4. Click Connect on the connector and sign in with GitHub. This is the step that matters: without it you are capped at 50 calls a day, with it you get 200 — free, same connection.
5. In a new chat, open the tools menu and enable Pipeworx (you should see ~38 tools).

https://gateway.pipeworx.io/oauth/mcp

https://gateway.pipeworx.io/pipeworx-catalog/mcp

Not signing in still works — you get 50 calls a day anonymously, no account needed. When you run out, Pipeworx asks your client to sign you in rather than just failing, so you can do it at that point instead.

Free Claude accounts can’t add custom connectors — that’s an Anthropic plan gate, not a Pipeworx one.

OpenAI’s visual workflow builder (platform.openai.com/agent-builder) connects to Pipeworx as an MCP tool — no code, no auth:

1. Open Agent Builder and create (or open) a workflow.
2. Click your Agent node → Tools → + → MCP Server → + Server.
3. Paste the URL below. Label it pipeworx. Authentication: None.
4. Pick the tools to expose (or leave all selected) and Add.

https://gateway.pipeworx.io/oauth/mcp

https://gateway.pipeworx.io/pipeworx-catalog/mcp

One-click deeplink — signs you in, 200 calls/day:

cursor://anysphere.cursor-deeplink/mcp/install?name=pipeworx&config=eyJ1cmwiOiJodHRwczovL2dhdGV3YXkucGlwZXdvcnguaW8vb2F1dGgvbWNwIn0=

Or the no-account deeplink — 50 calls/day:

cursor://anysphere.cursor-deeplink/mcp/install?name=pipeworx&config=eyJ1cmwiOiJodHRwczovL2dhdGV3YXkucGlwZXdvcnguaW8vcGlwZXdvcngtY2F0YWxvZy9tY3AifQ==

Or add to .cursor/mcp.json:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/oauth/mcp"
    }
  }
}

No account? Swap in https://gateway.pipeworx.io/pipeworx-catalog/mcp — same connection, 50 calls a day instead of 200.

Windsurf is now Devin Desktop (devin.ai/download) — same Cascade panel, same config path. Edit ~/.codeium/windsurf/mcp_config.json, save, then refresh Cascade’s MCP list:

{
  "mcpServers": {
    "pipeworx": {
      "serverUrl": "https://gateway.pipeworx.io/oauth/mcp"
    }
  }
}

No account? Swap in https://gateway.pipeworx.io/pipeworx-catalog/mcp — same connection, 50 calls a day instead of 200.

Via the UI: Settings → Cascade → Configuration → MCP servers → switch to the Cascade marketplace (not Devin Local) → Add custom MCP → paste the above → save.

Official extension — one command (or just ask Gemini CLI to run it):

gemini extensions install https://github.com/pipeworx-io/gemini-cli-extension

Note: Google is folding Gemini CLI into Antigravity CLI (mid-2026); the same extension/MCP mechanism carries over. The consumer Gemini web app does not support custom connectors — use the CLI or Gemini Enterprise.
