# Connect the free H/M Content Credentials MCP server

Canonical Streamable HTTP endpoint:

`https://agents.hogarmas.net/mcp/content-credentials`

Server card:

`https://agents.hogarmas.net/.well-known/mcp/content-credentials/server-card.json`

No account, API key or payment is required. The endpoint accepts status and H/M evidence JSON only. It does not accept source image, video, audio or PDF bytes.

## Important adoption boundary

Registry discovery does not install a server or grant an AI tool access. A person or workspace administrator must connect the endpoint to a compatible MCP client. An actual `tools/call` request, not a crawler or registry probe, is counted as a meaningful tool action.

## Codex

```bash
codex mcp add hm-content-credentials --url https://agents.hogarmas.net/mcp/content-credentials
codex mcp list
```

Equivalent `config.toml` entry:

```toml
[mcp_servers.hm_content_credentials]
url = "https://agents.hogarmas.net/mcp/content-credentials"
```

## ChatGPT desktop

Open `Settings > MCP servers`. If custom servers are enabled for the account or workspace, add the canonical endpoint above.

## Claude Code

```bash
claude mcp add --transport http hm-content-credentials https://agents.hogarmas.net/mcp/content-credentials
```

## First real task

```text
Use the H/M Content Credentials MCP server. Call run_content_credentials_self_check, then summarize the pass/fail result and every stated limitation. Do not send source media.
```

This deterministic self-check uses a synthetic fixture. It does not represent a user file, external activity or a truth verdict.

## Current free tools

1. `get_content_credentials_capabilities`
2. `triage_c2pa_validation_statuses`
3. `run_content_credentials_self_check`
4. `verify_content_credentials_envelope`
5. `verify_content_credentials_audit`
