Comparison Guides
Open Source Coding Agents, Compared
Every agent below ships under a licence GitHub could identify, and every one carries the same FARS review, so the numbers are comparable rather than borrowed from each project's own README. The table leads with the review; the sections under it carry each agent's own positioning, including where its documentation says it is not the right fit.

Compatibility here means full support, read from each agent's own AGENTS.md and documentation rather than inferred from the fact that it is an agent. Agents that only partly work under Claude Code are left out on purpose — a partial listing is the kind that costs you an afternoon.
12 reviewed agents comparedMCP Agents, Compared
MCP turns an agent's tool access into something you can audit and swap, which is why it shows up in almost every serious agent stack. These are the reviewed agents in the catalog that ship an MCP server, consume one, or both.
