Installation

pip install prodmcp              # Core (MCP tools, prompts, resources)
pip install prodmcp[rest]        # + FastAPI + Uvicorn for the unified server

Quick Start

from pydantic import BaseModel
from prodmcp import ProdMCP

app = ProdMCP("MyServer", version="1.0.0")


# --- Define Schemas ---

class UserInput(BaseModel):
    user_id: str

class UserOutput(BaseModel):
    name: str
    email: str


# --- Unified: Same handler as both MCP tool AND REST endpoint ---

@app.common(input_schema=UserInput, output_schema=UserOutput)
@app.tool(name="get_user", security=[{"type": "bearer", "scopes": ["user"]}])
@app.get("/users/{user_id}")
def get_user(user_id: str) -> dict:
    return {"name": "Alice", "email": "[e-mail]"}


# --- MCP-only Prompt ---

@app.prompt(name="summarize", input_schema=UserInput)
def summarize(user_id: str) -> str:
    return f"Please summarize data for user {user_id}"


# --- MCP-only Resource ---

@app.resource(uri="data://users", name="user_db", output_schema=UserOutput)
def fetch_users() -> list:
    return [{"name": "Alice", "email": "[e-mail]"}]


# --- Export OpenMCP Spec ---

spec = app.export_openmcp()
print(spec)

# --- Run the unified server ---

if __name__ == "__main__":
    app.run()  # REST at / (Swagger at /docs) + MCP SSE at /mcp/sse

Features

• Unified Framework — One ProdMCP instance replaces both FastAPI and FastMCP
• Decorator Stacking — @app.tool() + @app.get() on the same handler with @app.common() for shared config
• HTTP Methods — @app.get(), @app.post(), @app.put(), @app.delete(), @app.patch() (FastAPI-identical)
• MCP Primitives — @app.tool(), @app.prompt(), @app.resource() (FastMCP-identical)
• Schema-First — Pydantic models or raw JSON Schema for input/output definitions
• Validation Engine — Automatic input/output validation with structured error reporting
• Security Layer — Bearer, Basic, Digest, API keys, OAuth2, OpenID Connect
• Middleware System — Global before/after hooks (logging, rate limiting, tracing)
• Dependency Injection — Composable dependencies injected into handlers
• OpenMCP Spec — Auto-generated, machine-readable specification from code
• Unified Server — REST + MCP SSE on a single HTTP server (app.run())

Release Notes

Version 0.3.0 — Unified Framework Release

One framework. Both worlds. ProdMCP 0.3.0 makes ProdMCP a true drop-in replacement for FastAPI and FastMCP.

Key changes:

• Unified Architecture — FastAPI-style HTTP decorators + FastMCP-style MCP decorators on a single class
• @app.common() — Define schemas, security, and middleware once for stacked decorators
• app.run(transport="unified") — REST at / + MCP SSE at /mcp/sse on one server (new default)
• Expanded Security — HTTPBasicAuth, HTTPDigestAuth, APIKeyHeader/Query/Cookie, OAuth2PasswordBearer, OAuth2AuthorizationCodeBearer, OAuth2ClientCredentialsBearer, OpenIdConnect
• Migration Examples — fastapi_migration.py, fastmcp_migration.py, unified_example.py
• Bug Fixes — Fixed $ref paths in OpenMCP spec, security config propagation, and API key scheme naming

See CHANGELOG.md for the full changelog.

Version 0.2.0 — Initial Public API Release

• Decorator API: @app.tool(), @app.prompt(), @app.resource() with schema, security, and middleware support.
• Schema-First Validation: Pydantic BaseModel input/output validation with strict_output toggle.
• Security Manager: BearerAuth, ApiKeyAuth, CustomAuth with shorthand inline definitions.
• Dependency Injection: Depends() for async context resolution.
• Middleware Hooks: Global and entity-specific before/after lifecycle hooks.
• OpenMCP Spec Engine: app.export_openmcp() generates machine-readable specs.
• REST Bridge: app.as_fastapi() for MCP-to-REST testing.
