Mastercam MCP servers and AI agent skills

One community MCP server, Mastercam MCP, connects to Mastercam. Most of its 24 default tools review exported job data (tool lists, NC programs, cycle-time estimates, setup sheets) and work without Mastercam. On a licensed Windows workstation a NET-Hook add-in gives a limited live read path, with a Mastercam 2027 operation snapshot still under acceptance testing. It starts read only, and it can't post code, run a machine or execute arbitrary code. CNC Software's own AI assistant, Mastercam Copilot, is not exposed over MCP.

How AI connects to Mastercam

An MCP server or skill can only do what Mastercam lets programs do. Mastercam exposes 2 automation interfaces:

  • NET-Hook API (.NET): NET-Hook is Mastercam's .NET add-in API: an add-in built against the NET-Hook files for your Mastercam release runs inside Mastercam and can read the open job. CNC Software hosts the reference behind a sign-in at nethookdocs.mastercam.com. Mastercam MCP uses this route, and needs NET-Hook files matching your installed release, the matching .NET SDK and administrator approval to copy the add-in into the Mastercam folder. Documentation
  • Exported job data and NC files (Input files): Much CAM review doesn't need the live application: tool lists, posted NC programs and shop tool catalogues can be read as files. Mastercam MCP's portable tools work this way, comparing tool lists, checking straight and circular moves in NC code and estimating time, and flag anything they can't parse (cycles, macros, rotary moves) as unknown rather than safe.

What CNC Software offers

CNC Software includes Mastercam Copilot with Mastercam 2026.R2 at no extra cost for Mastercam CONNECT subscribers. It answers questions from Mastercam's help and knowledge base, searches training videos, and takes voice or text commands to edit feeds and speeds, create machine groups and operations and navigate the interface. The product page doesn't mention MCP or an API for outside agents.

What you can do with Mastercam and AI

  • Compare the tool list in a job with the tools a setup sheet or shop catalogue says are available.
  • Check an NC program's straight and circular moves and get a time estimate, with unsupported moves flagged for manual review.
  • Work out thread guidance from confirmed thread dimensions and draft setup notes for the operator.
  • Read a live Mastercam 2027 job's operation list on a licensed Windows workstation, keeping the server read only.
  • Propose an operation change as a before-and-after preview that the operator must approve before it is applied.

Questions

Is there a Mastercam MCP server?

One community server, Mastercam MCP (npm package mastercam-mcp, Apache-2.0). CNC Software doesn't publish an MCP server.

Can Claude program toolpaths in Mastercam?

Not through this server. It can draft an outside-diameter turning plan as a proposal and apply approved parameter changes, but it doesn't create Mastercam operations, generate toolpaths or post NC code.

Is it safe to connect to a live Mastercam session?

The server starts read only. Writes need a write profile, a hard read-only opt-out and an operator-approved preview tied to the document revision. Its NC review can't certify a program, so Mastercam Verify, machine simulation and a prove-out are still needed.

Does Mastercam Copilot work with Claude?

Not as far as CNC Software documents. Copilot runs inside Mastercam for CONNECT subscribers, and its product page mentions no MCP or external API.

AI-generated models, drawings and results must be checked by a qualified engineer before use.
