Rate limits
Default and authenticated rate limits for REST and MCP.
Rate limits
Brandymail applies Fastify rate limiting globally and tighter per-route budgets on MCP.
MCP (POST /mcp)
| Mode | Limit | Key |
|---|---|---|
| Anonymous | 30 / minute | Client IP |
Authenticated (Bearer bmk_…) | 120 / minute | API key id |
REST API
Global service rate limits apply. Prefer exponential backoff on 429 responses and reuse connections where possible.
When you need sustained higher throughput, contact Brandymail — organization keys unlock the documented MCP ceilings and attribution, not unlimited REST capacity.
