Environment variables
  • MCP_LOG_LEVELSets the minimum log level for output (e.g., 'debug', 'info', 'warn').
  • TOOLKIT_ENABLE_NET_DIAGNOSTICSRegister the gated toolkit_check_network tool. Off by default — leave off for hosted/shared deployments.
  • TOOLKIT_ENABLE_SYSTEM_INFORegister the gated toolkit_check_system tool. Off by default — only meaningful on a local deployment.
  • TOOLKIT_ALLOW_PRIVATE_NETWORKWith network diagnostics enabled, permit private/reserved/loopback targets. The second explicit gate; off by default.
  • TOOLKIT_GEO_API_KEYsecretAPI key for the geolocation endpoint, if it requires one. The default ip-api tier is keyless.
  • TOOLKIT_GEO_BASE_URLBase URL for an ip-api-compatible geolocation endpoint. Default is the keyless ip-api endpoint, which is plaintext HTTP.
  • TOOLKIT_GEO_CACHE_TTL_SECONDSGeolocation cache TTL in seconds. Geolocation is stable, so repeats are cached.
  • TOOLKIT_GEO_RATE_LIMIT_PER_MINMax geolocation requests per minute; excess requests are rejected with a retryable rate-limit error. Default 45 matches the ip-api free tier.
  • TOOLKIT_GEO_BATCH_RATE_LIMIT_PER_MINIndependent batch geolocation requests per minute; excess requests fail immediately with wait and recovery guidance.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
