fastapi-architect-mcp 0.1.0

MCP server giving Claude Code IDE-level intelligence for FastAPI projects

fastapi-architect-mcp

An MCP server that gives Claude Code IDE-level intelligence for FastAPI projects — semantic code navigation, safe renaming, route inspection, dependency trees, and Pydantic model analysis.

Instead of Claude reading files blindly, it calls structured tools backed by Jedi (Python language server) and Python's AST.

Tools

Tool	Description
find_references	Find all usages of a symbol across the project
rename_symbol	Safely rename a symbol across all files
go_to_definition	Jump to where a symbol is defined
get_completions	Get completion suggestions at a cursor position
list_routes	List all FastAPI routes with method, path, and handler
get_dependencies	Get the full Depends() injection tree for a handler
list_models	List all Pydantic models in a file
inspect_model	Inspect a Pydantic model's fields, types, and validators
find_model_usages	Find all usages of a Pydantic model across the project

Installation

pip install fastapi-architect-mcp

Configuration

Add this to your Claude Code settings (~/.claude/settings.json):

{
  "mcpServers": {
    "fastapi-architect": {
      "command": "fastapi-architect-mcp"
    }
  }
}

Then restart Claude Code. You can verify it's connected by asking:

"What MCP tools do you have access to?"

Usage examples

Once connected, you can ask Claude Code things like:

• "List all routes in main.py"
• "What are the dependencies of the get_users handler?"
• "Find all references to get_db across the project"
• "Rename get_db to get_session everywhere"
• "Inspect the UserCreate model in schemas.py"

Requirements

• Python 3.11+
• Claude Code (VS Code extension or CLI)
