Policy
Include a host when all of the following hold (see selection-policy.md):
- HTTPS Streamable HTTP MCP (
initialize+tools/listlike the app client). - Free to add (optional free API key allowed).
- A real end-user job, not a demo echo server.
A probe is attested live only when that initialize + tools/list handshake succeeds. Auth-optional hosts (Jina AI) need initialize without a key.
Replace this snapshot only via the refresh playbook.

Notes
- Jina AI still uses
requiresAuth: truein Kotlin so the add sheet shows a key field. The probe listed 22 tools without a key; search tools still need a free jina.ai key. remote.mcpservers.orgFetch and Sequential Thinking stay out (removed earlier).- Do not add replacement hosts without an explicit product decision.
