On 2026-11-01 the server answered initialize and tools/list without a sign-in. First answer in 497 ms.

• Its tools do none of the product's use cases we checked: Log lifts and runs together in one training week; Check weekly muscle load before choosing the next session.
• Checked on 3 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• list_archetypes

  The workout archetypes the generator makes, one per line: key, name, formats, minutes, line count, and the session slots it serves.

• list_equipment

  The equipment suggest_workouts' `equipment` takes, one per line: key: name, with "(machine)" on ergometers (rower, ski erg, bikes). Keys, names and common names ("echo", "row erg", "DB", "kb") all work.

• find_movements

  Movement slugs whose name holds `query` (e.g. "row", "sled"), for suggest_workouts' include and exclude, machines and runs first.

• suggest_workouts

  New workouts from our generator, as text. Ask this instead of writing workouts yourself. Nothing is saved. Example, two people with an echo bike, rower and ski erg, 40-60 min: suggest_workouts(count=5, people=2, minutes_min=40…

• vary_workout

  Variations of one library workout from our generator (no AI), as text, in its own format or another. Nothing is saved. A shortfall says what blocked it.

• generate_workouts

  New workouts unlike any in the library, from our generator (no AI), as text: evolved from the library's workouts and movements (more lines, fewer, other formats) into kinds it does not hold. For one person. Nothing is saved; other ones…

• report_workout

  Send Goblin Gains what the user thinks of a workout from these tools. Call it whenever the user points out a mistake (wrong equipment, a weight, a dose that cannot fit) or says a workout is bad or good: the words go to Goblin Gains…
