Plug MCP servers into agent runtimes.
MCP Inside Agent Frameworks is a free MCP Academy lesson on CoddyKit — lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the MCP Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Agents Need Tools Too
An agent framework runs a loop: the model thinks, picks a tool, sees the result, repeats. MCP is a tidy way to feed it those tools.
One Connection, Many Tools
Instead of wiring each tool by hand, your agent connects to an MCP server once and instantly gains everything that server advertises.
Frameworks Speak MCP
Popular agent runtimes add MCP support so you can drop a server in as a tool source, no custom glue code per framework.
Discover, Then Use
At startup the framework asks the server to list tools, then exposes them to the model like any other callable in the loop.
tools = await session.list_tools()The Loop Stays the Same
Your agent loop does not change much. MCP just supplies the tool definitions the model chooses from on each step.
Calling a Tool
When the model picks a tool, the framework forwards the call to the MCP server with call_tool and waits for the result.
result = await session.call_tool(
"get_weather", {"city": "Rome"})Mix Many Servers
An agent can attach several MCP servers at once, pooling a database server, a search server, and a files server into one toolbox.
Swap Tools Without Code
Because tools live behind servers, you can add or remove capabilities by changing config, not by rewriting the agent itself.
The Host Handles Plumbing
The framework acts as the host: it starts servers, manages connections, and translates between the model and MCP for you.
Why This Scales
One server can power many agents, and one agent can use many servers. That many-to-many reach is exactly what MCP was built for.
Keep Your Agent Logic
MCP does not own your agent. Your reasoning, planning, and memory stay in the framework; MCP only standardizes the tool layer.

How does MCP fit into an agent framework?
Recap
An agent framework connects to MCP servers, discovers their tools, and calls them inside its loop. Plug in capability, keep your logic. 🔌
