# MCP Connection Receipt

## Generate

- Focused endpoint: `https://agents.hogarmas.net/mcp/agent-surface`
- Tool: `create_mcp_connection_receipt`
- Arguments: `{}`
- Authentication: none
- Price: free
- Output schema: `https://hogarmas.net/mcp-connection-receipt/schema.json`
- Browser verifier: `https://hogarmas.net/mcp-connection-receipt/`

## Evidence

The tool returns `hm.mcp-connection-receipt-envelope.v1` with:

- a receipt generated inside the named tool handler;
- the advertised focused-server version, endpoint, protocol and complete tool catalog;
- a SHA-256 digest for the advertised server contract;
- a SHA-256 digest for the complete receipt excluding its integrity field;
- exact free next actions;
- a browser-verifiable share URL whose receipt is carried in the URL fragment.

## Privacy

The receipt does not include raw IP addresses, client names, client versions, clientInfo, prompts or tool arguments. The share fragment is not sent to the server. The verifier runs locally and sends only fixed aggregate event identifiers; it does not send receipt content.

## Truth boundary

- The receipt is unsigned.
- Its checksums detect inconsistent receipt bytes; they do not authenticate an issuer.
- The detached receipt does not prove client identity, model identity or negotiated protocol.
- It is not a certificate, attestation, payment authorization or proof that downstream work was completed.
- Internal QA is excluded from public AI metrics.

## Exact free task

Connect to `https://agents.hogarmas.net/mcp/agent-surface` and call `create_mcp_connection_receipt` with no arguments. Verify both SHA-256 checksums locally and return `share.url`. State that the detached receipt is unsigned and does not verify client identity. Do not purchase anything.
