agent-mcp-framework

agent-mcp-framework

A Python framework for building multi-agent MCP (Model Context Protocol) servers.

Compose multi-agent systems with sequential, parallel, conditional, and map-reduce pipeline patterns, agent lifecycle hooks, and structured outputs — and expose the result as MCP tools for Claude, VSCode, or any MCP-compatible client.

Features

• Agent abstractions — Agent, LLMAgent, FunctionAgent with lifecycle hooks
• Pipeline composition — Sequential, Parallel, Conditional, and MapReduce patterns
• MCP integration — Expose agent pipelines as MCP tools over stdio or SSE
• Output formatting — JSON, Markdown, and plain text output modes
• CLI — Run servers and pipelines from the command line
• Docker ready — Dockerfile, docker-compose, and container health checks
• CI — GitHub Actions matrix (Python 3.10–3.13): lint, tests, Docker build

Installation

pip install agent-mcp-framework

Quick Start

from agent_mcp_framework import Agent, AgentContext, AgentResult, SequentialPipeline, AgentMCPServer


class AnalyzerAgent(Agent):
    async def run(self, context: AgentContext) -> AgentResult:
        code = context.get("code", "")
        issues = []
        if len(code.splitlines()) > 500:
            issues.append("File exceeds 500 lines — consider splitting")
        if "import *" in code:
            issues.append("Wildcard imports detected")
        context.set("issues", issues)
        return AgentResult(success=True, output={"issues": issues, "count": len(issues)})


class ScorerAgent(Agent):
    async def run(self, context: AgentContext) -> AgentResult:
        issues = context.get("issues", [])
        score = max(0, 100 - len(issues) * 15)
        return AgentResult(success=True, output={"score": score, "grade": "A" if score >= 90 else "B" if score >= 70 else "C"})


# Compose agents into a pipeline
pipeline = SequentialPipeline("code-review", agents=[
    AnalyzerAgent("analyzer", description="Find code issues"),
    ScorerAgent("scorer", description="Score code quality"),
])

# Expose as an MCP server
server = AgentMCPServer("code-review-server", description="Multi-agent code review")
server.add_pipeline_tool(
    pipeline,
    name="review_code",
    description="Analyze code quality and return a score",
    parameters={"code": str},  # the input schema MCP clients see
)

if __name__ == "__main__":
    server.run()  # Starts MCP server on stdio

Docker

# Build and run locally
docker compose up --build

# Or build manually
docker build -t agent-mcp-framework .
docker run -p 8080:8080 agent-mcp-framework

Agent Types

Agent — Base class

Implement run() to define your agent's logic.

LLMAgent — Claude-powered agent

Built-in Anthropic client with complete() helper for LLM calls.

FunctionAgent — Quick inline agents

Wrap any async function as an agent without subclassing.

Pipeline Patterns

CLI

# Start an MCP server
agent-mcp serve my_project.server

# Run a pipeline directly
agent-mcp run my_project.pipeline --input '{"code": "import *"}'

# Show framework info
agent-mcp info

Project Infrastructure

• Dockerfile — Multi-stage build with health checks
• docker-compose.yml — Local development
• .github/workflows/ci.yml — CI pipeline (lint, test, Docker build)
