MCP

The Model Context Protocol (MCP) is becoming the shared interface for agent tool-use: a standard way for an agent to call external tools, data sources, and servers.

• Tools with first-class MCP support (Claude Code, Cursor, OpenCode, Cline, Goose) gain the whole ecosystem of MCP servers for free.
• For frameworks, MCP standardizes how an agent reaches outside the model, so custom integrations become portable rather than per-tool.
• Practical implication: when choosing a coding agent, MCP support is now table stakes, because it future-proofs the tool against new data sources and services.

MCP is covered as a facet across the directory at /tools; this page tracks why it matters and which tools implement it well.
