Developer-platform lead: AgentReady.org accepts either for the act-layer MUST. Agent builder: Coding agents use both; chat agents need MCP. A CLI runs in the agent's terminal; an MCP server runs remotely with OAuth. Stripe, Vercel and Neon now use their CLIs to configure their MCP servers. ## The sourced difference A CLI runs in the agent's terminal; an MCP server runs remotely with OAuth. Stripe, Vercel and Neon now use their CLIs to configure their MCP servers.

Registry in preview with API v0.1 frozen since 24 Oct 2025. | | What it does not do | Does not help agents that cannot run a shell, such as chat-only assistants; output formats differ by vendor. | Does not grade servers, verify registry entries, or prescribe a .well-known discovery file in the 2026-07-28 core spec; server cards are still Working Group work. | Read the full entries: [CLIs](https://agentmcpdirectory.com/standards/cli-as-agent-surface/) and [MCP](https://agentmcpdirectory.com/standards/mcp/). ## Seen in the directory 36 companies in the directory have a CLI package on record, out of 1,336. The figure is a floor: a package is checked only where a source names it. See [the CLI guide](https://agentmcpdirectory.com/guides/ship-a-cli-for-agents/). ## Seen in the shared crawl | Path | Top 10,000 found | Ora leaderboard found | | --- | --- | --- | | /.well-known/mcp.json | 19 of 7,470 (0.25%) | 66 of 3,366 (1.96%) | A path counts only when the answer is the right kind of document. Many sites answer these paths with an ordinary web page, which is not counted. See [the census](https://agentmcpdirectory.com/census/).
