Koskamo

OpenFab MCP

Provides instant parametric cost estimates for custom manufacturing processes including CNC, molding, sheet metal, 3DP, and PCB. It serves as an independent estimation service for autonomous agents, offering indicative quotes, lead times, and DFM feedback without fulfilling orders.

Endpoint and access

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http openfab-mcp https://openfab-22100483453.us-central1.run.app/mcp/

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add openfab-mcp --url https://openfab-22100483453.us-central1.run.app/mcp/

Cursor

Merge this server into .cursor/mcp.json in your project, then enable openfab-mcp in your MCP settings.

      "url": "https://openfab-22100483453.us-central1.run.app/mcp/"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http openfab-mcp https://openfab-22100483453.us-central1.run.app/mcp/

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
