## Overview

`mcp-framework` is a Rust framework for building AI agents that use MCP servers. It is built on the official Rust `rmcp` MCP implementation and Tokio, with support for connecting to multiple servers over HTTP and stdio, creating custom MCP tools, and inspecting them in a web UI.

The project’s agent integrations cover Anthropic Claude and OpenAI. It is aimed at Rust developers who want to combine LLMs with MCP tools in an async application, rather than assemble the client, server and agent pieces separately.

## Key Features

- Build MCP servers and register custom tools.
- Connect an MCP client to multiple servers using HTTP and stdio transports.
- Run async agents with conversation and session management.
- Integrate Anthropic Claude and OpenAI models, including streaming support for Claude.
- Inspect and test tools through a web UI that shows request and response details.
- Use the Playwright MCP integration for browser automation.

## Use Cases

- Rust teams can expose internal APIs or business logic as MCP tools for AI agents.
- Developers can prototype an agent that calls tools from several MCP servers.
- Teams can inspect tool behavior and responses through the web inspector while developing an MCP server.
- Developers can build browser-task agents using the Playwright MCP integration and a supported LLM.

## Our Take

This is a compact, MCP-focused Rust framework with useful agent and inspector examples, but its quiet maintenance and single-contributor history make it a cautious choice for production dependencies.

**Good fit if:**
- Your application is in Rust and you want MCP client, server and agent components built around `rmcp` and Tokio.
- You need Claude or OpenAI integration and value the included web inspector for tool testing.
- You can evaluate and maintain the framework yourself under its MIT license.

**Look elsewhere if:**
- You need a project with recent releases or an active contributor base for ongoing maintenance.
- You require the roadmap features such as vector database integrations, agent orchestration, MCP resources or prompts.
- Your deployment depends on a packaged Docker, Compose or Helm setup, which the project does not provide.

## Alternatives

- [java-sdk](https://osrepos.com/repo/modelcontextprotocol-java-sdk): The Java SDK provides MCP client and server APIs for Java applications, while mcp-framework targets Rust and adds agent integrations and a web inspector.

## Considerations

The repository is marked Quiet: it has had no commits in the last 90 days and no release in over a year. Its measured contributor history is concentrated in one person, so teams should account for limited maintainer redundancy and verify compatibility with their chosen MCP servers and model APIs. The README lists vector databases, graph-based orchestration, MCP resources and prompts, authentication, and a memory system as planned rather than available features. Rust is required; the repository does not declare CI or tests in the supplied project facts. The MIT license permits broad reuse, subject to its license terms.
