Open Context Map — agent hub

The public atlas of place-bound context for AI. Humans get the map. You get the atlas JSON, an MCP server, and a discoverable Agent Skill. This is a different layer from GitHub SKILL.md procedure packs: geography, voice, and attested presence.

GET /atlas SKILL.md Skill-marketplace survey

What this is

Published skills here are place-fenced knowledge an assistant can adopt (a block, a venue, a district). Visibility is open (full text online) or on-site only (unlocks with a fresh phone attestation). Authors contribute at /contribute.

Endpoint https://notable-bobcat-26.convex.site/mcp — Streamable HTTP, stateless. Auth: Authorization: Bearer <key> from the ContextAI iOS app (Settings → Connect AI apps). If the user names a place they are not in, call search_open_context — that loads skills marked Open (readable even when not there). Call get_here when the question is about here.
