2 sourcesShow HN: MCP-Compatible OpenAI Agents SDK
Hey HN,
OpenAI released the Agents SDK yesterday, which is great because of its simplicity. I just added MCP support for it, which is currently available as a fork here: https://github.com/lastmile-ai/openai-agents-mcp (and on pypi as the openai-agents-mcp package).
You can specify the names of MCP servers to give an Agent access to by
setting its `mcp_servers` property.
The Agent will then automatically aggregate tools from the MCP servers, as well as
any `tools` specified, and create a single extended list of tools. This means you can seamlessly use MCP servers, local tools, OpenAI-hosted tools, and other kinds of Agent SDK tools through a single unified syntax -- and have them interact in the same Agent run loop!
Everything else stays exactly the same.
```
agent = Agent(
name="MCP Assistant",
instructions="You are a helpful as
Read the rest
sistant with access to MCP tools.",
tools=[your_other_tools], # Regular tool use for Agent SDK
mcp_servers=["fetch", "filesystem"] # Names of MCP servers from your config file (see below)
)
```
The servers are configured in an `mcp_agent.config.yaml` file, very similar to how they are configured for Claude Desktop:
```
$schema: "https://raw.githubusercontent.com/lastmile-ai/mcp-agent/main..."
mcp:
servers:
fetch:
command: "uvx"
args: ["mcp-server-fetch"]
filesystem:
command: "npx"
args: ["-y", "@modelcontextprotocol/server-filesystem", "."]
slack:
command: "npx"
args: ["-y", "@modelcontextprotocol/server-slack"]
```
I have submitted an issue and PR into the openai-agents-python repo [2], and my plan is instead of a fork, I will create an extension package for MCP support (coming later today).
I was able to do this pretty quickly (got it working yesterday) because I've been building the mcp-agent library (https://github.com/lastmile-ai/mcp-agent), which makes MCP server aggregation/connection really easy. I did a Show HN about it a few weeks ago [3].
Wanted to share here to get community feedback on whether this is useful, which will help me decide if I should dedicate more time to it.
