## Everything on MCP sign-in

### Research and data

- 1 Nov 2026: [MCP servers everywhere, agents nowhere](https://agentdrives.com/findings/mcp-without-access.md?via=md). 105 of 174 products with an MCP server keep an AI agent out.
- 1 Nov 2026: [MCP sign-in: which servers let an AI agent register itself?](https://agentdrives.com/findings/mcp-sign-in.md?via=md). An AI agent can register itself as a client at 55 of the 59 MCP servers whose sign-in we read. At 33 of them, the only way is dynamic client registration (DCR), which the MCP spec deprecated in its 2026-07-28 version.
- 1 Nov 2026: [Most products that stop an AI agent at sign-up still offer it an API, MCP or CLI](https://agentdrives.com/findings/stopped-at-sign-up.md?via=md). 114 of the 117 products that stopped our agent at sign-up still offer it an API, an MCP server or a CLI (97%). Of the 77 products that let it in on its own, 77 do (100%).
