Connect your AI assistant

Gnomon Context holds what the open web doesn’t: the situations real people report — what they need, offer, dream of, organise or want to share — each recorded along the journalistic W-questions: who, what, when, where, why, how. Give your assistant the MCP server and it can search them, find the other side, see what is happening, and file its user’s own situation with their consent.

MCP endpoint

https://gnomoncontext.com/api/mcp

Streamable HTTP. Reads are public (rate-limited). Publishing — filing, liking, commenting, committing — needs an account: the first time, your assistant asks you to sign in with a code sent to your email address.

ChatGPT — as an app

Once it’s published, find Gnomon Context in the ChatGPT App Directory (chatgpt.com/apps, or the apps menu in the composer) and turn it on — no setup needed.

ChatGPT — connect it yourself

To use it before it’s listed, or to test your own build:

1. Settings → Apps → Advanced settings → Developer mode (on).
2. Create app and paste the MCP endpoint above. It must be a public HTTPS URL — localhost can’t be reached by ChatGPT.
3. In a chat, open the Developer Mode tool and ask: “Search Gnomon Context for language exchange in Geneva.”

Claude

Add a remote MCP server pointing at the same URL:

{
  "mcpServers": {
    "gnomoncontext": {
      "url": "https://gnomoncontext.com/api/mcp"
    }
  }
}

For local development with the stdio server, see .mcp.json in the repo.

  File one person's situation in their own words, with the W-questions they answered (who, what, when, where, why, how, purpose, means, amount, origin).
• search_situations read
  Search listed situations by kind, topic, theme, place, modality, time shape, compensation and language, with free text ranked semantically.

• get_situation read
  One situation in full: its facets, time, place, event status, comments and links.

• fetch read

Filing and engaging

record_situation files one person’s own situation, in their own words, with their consent. Their words and their contact are never published: public reads return an anonymized summary and the structured answers, and contact is exchanged only when both sides opt in. Documents for agents: https://gnomoncontext.com/s/{id}.md and https://gnomoncontext.com/t/{topic}.md · descriptor: /.well-known/mcp · plaintext: /llms.txt.

Support

Trouble signing in or connecting an assistant, a question, or a request about something you published: write to info@gnomonpractice.com, and quote the situation’s id if it is about one.
