MCP Compatibility Matrix

MCP Compatibility Matrix explains the compatibility layer of MTPX with practical guidance for building inspectable, tool-using agents.

01Orientation

MCP Compatibility Matrix belongs to the mcp track. The page breaks the idea into responsibilities, implementation rules, failure modes, and the signals you should expose in a product UI.

Use this when

Use this when you need to understand how mcp compatibility matrix affects a real MTPX agent before you wire it into an application.

What mcp compatibility matrix owns in the runtime.
How it connects to planning, tool execution, events, providers, or storage.
What to log, test, and expose to users when this layer is active.
Common mistakes that make agent systems hard to inspect.

02 / minimal pattern

from mtp import Agent
from mtp.providers import Groq

agent = Agent.MTPAgent(provider=Groq(), tools=tools)
print(agent.run("MCP Compatibility Matrix: explain the next runtime step.", max_rounds=4))

Read

Understand where MCP Compatibility Matrix sits in the agent loop before adding abstractions.

Wire

Connect the smallest useful provider, registry, store, or event stream first.

Observe

Expose events, logs, results, and failure states while the runtime is still moving.

Harden

Add policy, tests, retries, and audit traces after the behavior is visible.
