3D printing filament and materials knowledge MCP server
Overview
Local MCP server giving assistants a searchable 3D printing filament and material science knowledge base with 8 lookup, comparison and troubleshooting tools.
- What you can do
- Search and look up filaments by name, material, manufacturer or color, and get full specs for a specific filament
- Browse manufacturers and material types with filament counts
- Read authoritative material profiles and compare two to three materials side by side
- Get ranked material recommendations for stated requirements and diagnose print problems with material-specific fixes
- When to use it
- Useful when working with 3D printing: choosing a filament or material for a job, comparing materials, or troubleshooting print defects and needing material-specific guidance.
- Requirements
- Runs as a local process via npx (Node.js required). Data is embedded, so no API keys, accounts or network calls at runtime. Desktop-only; configured in a desktop client such as Claude Desktop.
Installation
In SourceWeft
- Open 3dprint Oracle in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

Score
50% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
- Reached in the last 30 days25 pts
Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
- Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
