Claude
Add Endless to Claude on the web, in the desktop app, or to Claude Code in your terminal — one address and one sign-in.
Claude reaches Endless through a custom connector — Anthropic's name for a remote MCP server you point Claude at yourself. There is no one-click button to press: you paste one address and sign in.
https://mcp.endless.appThe same address everywhere — web, desktop, phone and terminal. Copy it exactly: no trailing slash, nothing after it.
Claude on the web, desktop and phone
Add it once from a browser or the desktop app and it follows your Claude account, the mobile apps included. The connection runs between Anthropic's servers and ours, so nothing depends on the device you're holding.
Open your connectors
In Claude, go to Customize → Connectors.
Add a custom connector
Press +, then Add custom connector, and paste the address above. Leave Advanced settings alone — Endless needs no client credentials from you.
Sign in with Endless
Press Add. A window opens on your Endless sign-in, asks you to approve the access, and returns you to Claude with the connector listed.
Check it
Ask Claude: "Ask Endless who I am." It should answer with your account, your workspaces, and which one it's reading.
On a Claude Team or Enterprise plan, an owner adds the connector once for everyone; each member then presses Connect on it and signs in with their own Endless account. Nobody inherits anybody's access.
Claude Code
Add the server
claude mcp add --transport http endless https://mcp.endless.appAdd --scope user to have it in every project rather than only the current one.
Sign in
Run /mcp, choose endless, and complete the sign-in in the browser window that opens.
claude mcp login endless does the same thing from the command line.
Check it
/mcp should show endless as connected, with its ten tools.
--scope project writes the server into the repository's .mcp.json, which
is shared with everyone who clones it. That's fine — the file holds an address
and no secret, and each teammate still signs in as themselves.
What to ask for
The tools are named for what they do, so plain requests reach them. Some that work well:
- "Search my Endless assets for the Q3 launch deck."
- "Find the transcript where we talked about the pricing change, and quote the part about annual plans."
- "What videos did we make for the summer campaign?"
Search matches text inside a file, not only its title — a transcript's words, a document's body. Ask for the file in full when the preview isn't enough.
When it doesn't work
The sign-in window ends nowhere
Remove the connector and add it again, checking the address for a stray slash or path. If it fails a second time, the sign-in — not Endless — is what to look at: sign in to Endless in the same browser first, then retry.
It says it can't tell which workspace
Expected on an account in more than one. The refusal lists them; name the one you want and it switches, then remembers for 90 days.
A file you know exists doesn't come back
Either you're in the other workspace, or the asset is private to a colleague. Claude sees exactly what your account sees — see assets and visibility.
It won't create or edit anything
By design. The catalog reads; generating, editing and spending stay in Endless.
