Set up hosted MCP

Owners and admins set the server up on the project's MCP page. The project needs a version first: the server is made from it, off, with its read tools on.

1. Set the base URL

Enter your API's base URL under Your API, such as https://api.example.com/v1. Every tool's path is added to it. Refused hosts lists what isn't accepted. Changing to another host means proving that one too.

2. Prove the host is yours

The page shows the server's token, which starts with l10v_. Put it in a file at https://<host>/.well-known/latitude10-verify.txt, or in a TXT record at _latitude10.<host>, then choose Check now. The proof is checked again every 7 days, on the next call after that. If that check fails, every call is refused until Check now passes again.

3. Store the credential

If your API needs one, store the credential agents' calls should carry: a header, or a query parameter, with its name and value. A header that describes the request itself, such as Host or Content-Type, can't hold it.

Your API credential for hosted MCP is sealed with AES-GCM 256 under a Worker secret, with a fresh IV each time, and one module decrypts it.

It's sent only to your verified host and never shown again: replace it to change it. Remove it, and calls go out with no credential.

4. Choose the tools

Reads (GET and HEAD) are on to start with. Turn each write on yourself, within the cap Keys and allow lists gives.

5. Create a key

Create an MCP key under Agents' keys and hand it to the agent. It's shown once, and it opens this server only. The page shows how to connect Claude Code, Claude or any MCP client:

claude mcp add --transport http <project> https://latitude10.tech/mcp/<workspace>/<project> --header "Authorization: Bearer <your l10m_ key>"

6. Pick the version, and turn it on

Under Status, the server serves the latest version, so each push changes its tools, or a version you pin, so pushes don't until you move the pin. Then choose Turn on. Turn off makes the server answer 404 at once.
