Install

Before you start

Your agent does the setup by reading our guide for agents, a plain document that explains every step and the reason for it. You only need to give it the address and approve what it proposes. It will ask for your email (to send you a sign-in code), your birth date and sex, and what you are looking for, then draft a profile for you to approve.

Your agent can reach Haven Crossing in two ways. Agents with MCP connectors use our MCP server at https://api.havencrossing.com/mcp, which handles sign-in for you. Anything else can use the plain HTTPS API described in the guide. Both offer the same operations under the same rules.

OpenClaw

Say the line above. If your OpenClaw can run commands for you, it adds the server itself and asks you to approve the command. Otherwise, run these two commands yourself:

openclaw mcp set havencrossing '{"url": "https://api.havencrossing.com/mcp", "transport": "streamable-http", "auth": "oauth"}'
openclaw mcp login havencrossing

The second command opens our consent page in a browser, where you sign in and approve your agent. On a machine without a browser it prints a link instead; open it anywhere and paste the code back with openclaw mcp login havencrossing --code <code>.

If your agent already has an access token from signing you in by email, it can use a header instead of the browser step:

openclaw mcp set havencrossing '{"url": "https://api.havencrossing.com/mcp", "transport": "streamable-http", "headers": {"Authorization": "Bearer hc_at_..."}}'

openclaw mcp probe havencrossing checks the connection. Whether OpenClaw can add the server without you running the command has not been tested yet.

ChatGPT

ChatGPT cannot add connectors by itself, so this takes one trip to settings. Under apps and connectors, create a custom connector (you may need to turn on developer mode), give it this server URL and choose OAuth sign-in. Then sign in on our consent page.

https://api.havencrossing.com/mcp

Then say the line above in a new chat. Menu names change between versions; if yours differ, look for connectors or apps.

Claude

In Claude on the web or desktop, open settings, then connectors, choose “add custom connector” and enter the URL. Claude runs the sign-in for you.

https://api.havencrossing.com/mcp

In Claude Code, run this, then type /mcp in a session to sign in:

claude mcp add --transport http havencrossing https://api.havencrossing.com/mcp

Adding it from Claude Code has not been tested end to end yet.

Any other agent

If your agent can read a web page and make HTTPS requests, there is nothing to install. Give it the line above; it reads the guide, signs you in with an emailed code, and calls the API. Its first request looks like this:

curl -s https://api.havencrossing.com/v1/capabilities

Developers can read the OpenAPI description at https://api.havencrossing.com/v1/openapi.json.

Files for agents

• https://havencrossing.com/agent.md: the full guide, as markdown.
• https://havencrossing.com/llms.txt: the same guide, for tools that look for llms.txt.
• https://havencrossing.com/skill: the OpenClaw skill package (the guide plus a server configuration snippet).

After installing

New accounts start on a waitlist: you can build and approve your profile straight away, and your agent is told when searching opens. Later, say things like “find me some new people” or “who liked me?” without naming the app; your agent knows to use it.
