Protocol
The USB-C port for connecting agents to tools and data.
An open protocol for connecting AI agents to external tools and data sources through a standard interface, so a capability built once can be reused across any MCP-compatible agent instead of re-integrated per framework.

Promoted to sitemap because coverage is deep enough.
Model Context Protocol (MCP) is an open standard, introduced by Anthropic, for wiring agents to the outside world: tools, files, APIs, and data sources exposed through one common interface. Instead of every framework inventing its own integration shape, an MCP server publishes a capability once and any MCP-compatible agent can use it.
Its significance is ecosystem-level. As agent SDKs and harnesses converged, MCP became a shared connective tissue, which is why it increasingly shows up as the way SDKs expose external capabilities. For operators it is also a trust-boundary question: an MCP server is another component your agent reaches, so the same provenance and least-privilege discipline that applies to skills applies here.
A minor Langfuse release adds the ability to delete evaluators across UI, API, and MCP. The unglamorous feature signals where the agent observability market actually sits on the evolution curve.
OpenClaw 2026.6.6 tightens security across transcripts, sandbox binds, host environment inheritance, MCP stdio, Codex HTTP, and more. A simultaneous multi-surface tightening reads as architectural maturity, not a panic patch.
Claude Managed Agents prices the harness at $0.08 per session-hour. The number is small. The structural shift it announces is not.
