Kaiord MCP

The Kaiord MCP server exposes fitness file conversion, validation, and inspection tools to AI agents. It supports converting between FIT, TCX, ZWO, GCN, and KRD formats, validating workout structures, and extracting workout metadata for analysis.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What you can do with it

  • Convert fitness files between FIT, TCX, ZWO, and KRD formats
  • Validate KRD JSON against the schema
  • Inspect and summarize fitness file metadata
  • Compare two fitness files to show differences

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Kaiord is a fitness data framework. KRD is the canonical JSON format — all conversions go through KRD. BEFORE creating or editing KRD documents, call the kaiord_get_format_spec tool to get the full specification. Use kaiord_list_formats to discover all supported formats (FIT, TCX, ZWO, GCN, KRD). Use kaiord_convert, kaiord_validate, kaiord_inspect, kaiord_diff, kaiord_extract_workout and kaiord_round_trip_validate on inline content: send text as is and FIT as base64. Only structured workouts are accepted. FIT output comes back as base64 text.

kaiord_convert
Advertised by the server during the last successful anonymous check.

Convert between fitness data formats (FIT, TCX, ZWO, GCN, KRD). FIT output is returned as base64 text unless output_file is given. On the remote endpoint, ZWO input is checked for well-formedness only, not against the XSD, and only structured workouts are accepted.
