Registration with MCP Gateway

After installing, Matrix Hub can register entities with MCP Gateway via its admin API.

What Gets Registered

• Tools: POST /tools with name, integration_type (REST|MCP), request_type, url, input_schema, and optional headers/annotations.
• MCP Servers: POST /gateways with name, url, transport (HTTP/SSE/STDIO/STREAMABLEHTTP), and optional auth.
• Discovery of tools is automatic after registration; no separate endpoint needed.
• Resources / Prompts (optional): added via POST /resources / POST /prompts.

Idempotency & Conflicts

• Re-registration with identical payloads may yield 409 Conflict; Matrix Hub surfaces this in the install results.
• Admin token is required; set MCP_GATEWAY_TOKEN.

Security

• Use Gateway over TLS.
• Store auth tokens outside source control (.env, secret manager).
