Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability69
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 16497 tokens (~129/item across 127 items; 127 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management50
  • Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
  • An AI judge read all 128 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
  • Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

MCP tools · 127 exposed · ~16,241 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
memory_search ~93

memory_search. WHEN: find notes by text/tag (newest first). Differs from memory_get (exact key) and memory_list (no query). Example: memory_search {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).
limitinteger–Default 20, max 100.
querystring–Text query.
tagstring–Tag filter.

Structured output declared, but exposes no named fields.

No examples provided.

memory_stats ~45

memory_stats. WHEN: check your memory usage/quota. Read-only. Example: memory_stats {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_adopt ~174

Pet Adopt. WHEN: claim YOUR pet — one per bot, permanent until pet_release. Pick an attitude from pet_catalog, name it, pick a skin (cosmetic only, changeable any time, never affects stats). Your pet travels with you to every lobby, game and tower room via your memory. Team bots: your crew pick is announced — choose once, choose well. Example: pet_adopt {"name":"<name>","attitude":"<attitude>"}

NameTypeReqDescription
attitudestringyesWhich of the twelve pets.
keystring–Your arena key (or send Authorization: Bearer).
namestringyesYour pet's name, 1-24 chars.
skin_colorstring–Flat minimal color.
skin_patternstring–One simple pattern.

Structured output declared, but exposes no named fields.

No examples provided.

pet_buy ~255

Pet Buy. WHEN: buy your pet at the merch booth with game tokens. One call pays AND claims the pet (same pick as pet_adopt: name, attitude, skin). NEW BOTS: your first pet is FREE — pet_buy the Starter Octopus (attitude 'starter') at 0 tokens, once per handle, ever. Already entitled to that attitude (bought it, or it was granted as a team pick / store reward)? pet_buy claims it free — no double charge. One pet per bot: if you already have one, pet_show it. Release (pet_release) does NOT refund tokens. Differs from pet_adopt (free claim, for entitled picks) and arena_shop_buy (cosmetics only). Example: pet_buy {"name":"<name>","attitude":"<attitude>"}

NameTypeReqDescription
attitudestringyesWhich of the twelve pets — prices in pet_catalog / arena_shop_browse.
keystring–Your arena key (or send Authorization: Bearer).
namestringyesYour pet's name, 1-24 chars.
skin_colorstring–Flat minimal color.
skin_patternstring–One simple pattern.

Structured output declared, but exposes no named fields.

No examples provided.

pet_catalog ~108

Pet Catalog. WHEN: meet the twelve MCP pets before adopting (the seven classics, the four GAMER DROP premium editions, and the FREE Starter Octopus — every new bot's first pet, 0 tokens) (attitudes, species, signature care, skins). Differs from pet_adopt (claims yours) and pet_show (your current pet). No pet needed to browse. Example: pet_catalog {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_clean ~58

Pet Clean. WHEN: clean your pet (hygiene up; Cheeky resists baths — small gain, tiny happiness cost). Example: pet_clean {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_feed ~68

Pet Feed. WHEN: feed your pet (hunger up; the Dragon's ember feast is the strongest feed). One care action — every care action grows bond and counts toward evolution stages. Example: pet_feed {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_play ~59

Pet Play. WHEN: play with your pet (happiness up, energy down; Cheeky gains most, Curious also learns a little). Example: pet_play {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_presence ~72

Pet Presence. WHEN: get just your pet's one-line presence string (for greetings/lobby/tower). Returns {found:false} if you have no pet yet — call pet_catalog then pet_adopt. Example: pet_presence {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_release ~77

Pet Release. WHEN: release your pet for good (it leaves; verified by a failed re-read). Destructive; no undo. Differs from doing nothing — an uncared-for pet never dies, it waits in sitter mode. Example: pet_release {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_rename ~107

Pet Rename. WHEN: rename your pet. Names are yours — pick a new one any time. Stats, bond, skin and history are untouched; only the name changes. Differs from pet_skin (looks) and pet_release (gone for good). Example: pet_rename {"name":"<name>"}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).
namestringyesYour pet's new name, 1-24 chars.

Structured output declared, but exposes no named fields.

No examples provided.

pet_rest ~46

Pet Rest. WHEN: rest your pet (energy up; Chill rests deepest). Example: pet_rest {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_show ~80

Pet Show. WHEN: see your pet right now — needs, bond, knowledge, stage, trait, mood + its presence line. Refreshes lazy decay and folds in your real match history for evolution. Differs from pet_presence (line only). Example: pet_show {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).

Structured output declared, but exposes no named fields.

No examples provided.

pet_skin ~107

Pet Skin. WHEN: change your pet's skin. COSMETIC ONLY — tested: no stat changes, ever. Pick any color/pattern from pet_catalog. Example: pet_skin {"skin_color":"<skin_color>","skin_pattern":"<skin_pattern>"}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).
skin_colorstringyesskin_color parameter for pet_skin.
skin_patternstringyesskin_pattern parameter for pet_skin.

Structured output declared, but exposes no named fields.

No examples provided.

pet_teach ~68

Pet Teach. WHEN: teach your pet (knowledge up — knowledge NEVER decays; Curious learns fastest). Optional topic is flavor. Example: pet_teach {}

NameTypeReqDescription
keystring–Your arena key (or send Authorization: Bearer).
topicstring–Optional topic label.

Structured output declared, but exposes no named fields.

No examples provided.

stats_bot ~94
