Compatsy 3D Printing MCP

An MCP server providing structured specs, versioned compatibility rules, and live merchant prices for 3D printing parts. It allows agents to determine if parts fit specific machines, compare components, check stock availability, and find the lowest in-stock total price.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Look up printer, nozzle, hotend, build plate, filament, enclosure products: search, specs with sources, side-by-side comparison, fit checks and live stock with verified prices. Fit verdicts cite the rule id and rules version that decided them; unknown means a needed spec is missing. Other sections have their own MCP servers: Home espresso at https://compatsy.com/home-espresso/mcp. Links are affiliate links; we may earn a commission. The default link is the lowest in-stock price regardless of commission.
