Claude Connectors talks to Agent Update over MCP. The server is https://api.tryagentupdate.com/v1/mcp, the transport is Streamable HTTP, and the credential is one header.
Where it goes: Settings -> Connectors -> Add custom connector
Setup
Settings → Connectors → Add custom connector

The value box takes the complete header value. Claude adds no prefix of its own. Header auth (static_headers) is Beta and rolled out selectively, so many users see no Request headers section at all. Header names come from an allowlist (authorization, x-api-key, x-auth-token), you get at most 4 headers, and values are never shown again once saved. On Team and Enterprise an Owner adds the connector under Admin settings → Connectors and members then click Connect. That means one admin enters the credential and the whole org shares it; it is not per-user. Open bug anthropics/claude-ai-mcp#644: the custom connector ignores the configured request header and falls into a broken OAuth flow. Test on a real account before telling users this works.
Check it worked
Ask the agent to text you. A 401 means the token is wrong, or the word Bearer is in there twice. No tool at all means the transport string is wrong. Both are covered in troubleshooting.

The five tools and their arguments are on the MCP page. The same tools over plain HTTP are on the REST page. Every other tool is on the docs index.
