Fabworks MCP Server

Connect an AI agent to Fabworks to create manufacturing quotes from STEP files.

The Fabworks MCP server lets an AI agent search the manufacturing catalog, upload STEP files, create quotes, review pricing and DFM results, update quote parts, and check orders.

Connect an agent

Copy this prompt into an agent that supports remote MCP servers:

Prompt for an AI agent
Add the Fabworks remote MCP server to this agent.

Name: Fabworks
URL: https://api.fabworks.com/mcp
Transport: Streamable HTTP
Authentication: OAuth

Configure the server and start OAuth. If you cannot edit your MCP
configuration, give me the exact steps for this client. Then list
the Fabworks tools to verify the connection.

OAuth opens a Fabworks sign-in page. MCP clients that support custom headers can also use a Fabworks user or organization API key:

Authorization header
Authorization: Bearer $FABWORKS_API_KEY

Keep API keys in an environment variable or secret store. Do not paste a key into chat or commit it to a repository.

Install the Fabworks plugin

Install the MCP configuration and Fabworks agent skills together:

Terminal
npx plugins add FabworksHQ/fabworks-plugin

You can also install only the quoting skill:

Terminal
npx skills add FabworksHQ/fabworks-plugin --skill quote-with-fabworks

Quote STEP files

Use this workflow:

  1. Call find_materials to get exact material and finish IDs.
  2. Call create_upload for each STEP file and upload the file to the returned signed URL.
  3. Call create_quote with the upload IDs, quantities, names, material ID, and finish ID.
  4. If processing continues, call get_quote. It waits for a result by default.
  5. Review the price, manufacturing configuration, DFM results, and checkout URL with the user.

Do not send STEP files as base64. The signed upload keeps file bytes out of the agent context. Do not select a suggested material without user confirmation. Exact tube searches treat box, square, and rectangular as the same profile family.
