Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
PEERINGDB_API_KEYOptional, secret | A free PeeringDB API key. Recommended, not required: it raises the rate limit, and every tool works without one. |
PEERING_MCP_CACHE_TTLOptional | How long a cached upstream response stays usable, in seconds. |
PEERING_MCP_CACHE_DIROptional | Where the on-disk cache lives. Defaults to $XDG_CACHE_HOME/peering-mcp. |
PEERING_MCP_NO_CACHEOptional | Set to 1 to disable caching. Slower, and harder on the upstream APIs. |
PEERING_MCP_TIMEOUTOptional | Per-request timeout in seconds. |
PEERING_MCP_MAX_RETRIESOptional | Attempts before an upstream failure is reported. |
