Agent Frameworks

AllMCP exposes a standard MCP HTTP endpoint (Streamable HTTP / SSE), so any framework with MCP support can connect using just the URL and your API key. There’s no AllMCP-specific SDK to install.

Browse providers Get your API key

Connection parameters

Every framework integration needs these two things:

URL:    https://go.allmcp.co/mcp/
Header: X-API-Key: YOUR_API_KEY

If your framework can only set a standard Authorization header, use the Bearer form instead:

Authorization: Bearer YOUR_API_KEY

For multi-user setups, append ?user_id=<id> to the URL:

https://go.allmcp.co/mcp/?user_id=USER_ID

The general pattern

Most Python frameworks follow the same shape:

# 1. Create the MCP client
mcp_client = FrameworkMCPClient(
    url="https://go.allmcp.co/mcp/",
    headers={"X-API-Key": "YOUR_API_KEY"},
)

# 2. Get the tools
tools = await mcp_client.get_tools()

# 3. Pass tools to your agent
agent = YourAgentFramework(llm=..., tools=tools)

# 4. Run
result = await agent.run("List my CRM contacts")

Pick your framework from the list above for the exact syntax.
