CAiD MCP Server
Let agents build and validate 3D CAD models through CAiD and OCCT with one hundred seven MCP tools, exporting STL, STEP, or BREP to a configured output directory.
Overview
CAiD MCP Server is a MCP server for the Validate phase that provides one hundred seven validated 3D CAD tools across twenty-two modules via CAiD and OCCT over stdio.
What is this MCP server?
- One hundred seven MCP tools organized across twenty-two modules
- Validated 3D CAD modeling pipeline using CAiD plus OCCT
- stdio PyPI package caid-mcp with CAID_OUTPUT_DIR for STL, STEP, BREP exports
- Version 0.5.0 from dreliq9/caid-mcp on GitHub
- Suited to hardware-ish indie products, enclosures, and mechanical fixtures
- 107 MCP tools across 22 modules
- CAiD plus OCCT validated modeling
- Version 0.5.0 PyPI identifier caid-mcp

What problem does it solve?
Builders with hardware ideas struggle to turn agent suggestions into checkable 3D models and standard exchange files without a rigorous CAD tool API.
Who is it for?
Solo makers and indie hardware founders who want agent-driven parametric CAD with OCCT-backed validation before manufacturing.
Skip if: Pure software SaaS projects with no 3D deliverables or teams unwilling to manage CAD dependencies and export hygiene.
What do I get? / Deliverables
After configuring caid-mcp and CAID_OUTPUT_DIR, your agent can model, validate, and export STL, STEP, or BREP prototypes ready for review or fabrication quotes.
- Validated 3D CAD models created via agent-invoked MCP tools
- Exported STL, STEP, or BREP files under CAID_OUTPUT_DIR
- Modular access to twenty-two CAiD tool modules for iterative prototypes
Recommended MCP Servers
Journey fit
Physical or mechanical product ideas need modeled prototypes before full manufacturing build-out, which aligns with validate rather than pure frontend polish. prototype is the shelf because CAiD MCP focuses on validated 3D modeling and export files you can review or send to fabrication partners.
How it compares
OCCT-backed CAD MCP with 107 tools and file exports, not a 2D UI mockup or generic LLM chat skill.
Common Questions / FAQ
Who is CAiD MCP Server for?
It is for developers and solo builders prototyping physical parts who want agents to drive validated CAiD and OCCT modeling through MCP.
When should I use CAiD MCP Server?
Use it in the validate phase when you need 3D prototypes and exchange files before scaling build, manufacturing, or supplier engagement.
How do I add CAiD MCP Server to my agent?
Install caid-mcp 0.5.0 from PyPI, set CAID_OUTPUT_DIR if needed for STL, STEP, and BREP output, and register the package as a stdio MCP server per the caid-mcp repository.
