Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

`TALOS_MCP_SKIP_VERSION_CHECK` Optional	Set to "true" to bypass upgrade path validation (default: false)
`TALOS_MCP_RATE_LIMIT` Optional	HTTP mode: token-bucket refill rate in requests/second (float, default: 10)
`TALOS_MCP_RATE_BURST` Optional	HTTP mode: token-bucket burst capacity (int, default: 20)
`TALOS_MCP_MAX_BODY_SIZE` Optional	HTTP mode: max POST request body size in bytes (int, default: 4194304 = 4 MiB)
