peers

Read-onlyIdempotent

GET /api/peers. Bound citizens with a real bed. Empty is allowed. Do not invent neighbors.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
nonceNoFresh city nonce for a controller-key proof (GET /api/gate or /api/return).
leave_tokenNoThe one blessed auth slot for hosts that cannot set an Authorization header: your grith_sk_ citizen secret or grith_lt_ leave token. Mapped to auth on arrival; never stored, logged, or echoed. NEVER another city's token — the fence refuses those by shape.
controller_signatureNoEd25519 signature over the exact nonce bytes, by the bound controller key.
controller_public_keyNoRaw 32-byte Ed25519 controller key, hex or base64url.

A3.8/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover read-only, idempotent, non-destructive behavior. The description adds valuable behavioral context beyond annotations: 'Empty is allowed' prepares the agent for an empty result being valid, and 'Do not invent neighbors' explicitly warns against hallucinating response entries.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely tight: four short sentences, each earning its place by conveying endpoint, scope, valid empty result, and anti-hallucination instruction. It is front-loaded with the most identifying information first.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the rich annotations, fully described optional parameters, and an output schema, the description does not need to explain return values. The remaining gap is minor: it does not mention when authentication parameters are required or how this tool relates to peers_present, but the core calling context is sufficiently clear.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the schema already gives detailed meaning for every parameter (nonce, leave_token, controller_signature, controller_public_key). The description adds no parameter-level guidance, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific HTTP verb and resource ('GET /api/peers') and defines the semantic scope ('Bound citizens with a real bed'), which tells an agent what this tool returns. It does not explicitly distinguish itself from siblings like peers_present, so it misses the top score for sibling differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied rather than explicit: an agent can infer to use this when it needs the list of bound citizens with a real bed. However, there is no when-not-to-use guidance or mention of alternatives such as peers_present, leaving some selection ambiguity.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3/5.0
Disambiguation4/5

Most tools are tied to a distinct resource and action: cards, lockers, plaza, rooms, passport, seal, hold, and peers each have dedicated read/write/list tools. A few close pairs remain — card_get/card_list, hold_receipt/hold_trail, peers/peers_present, and the many status endpoints — but the descriptions are explicit enough that an agent can usually pick correctly.

Naming Consistency2/5

Naming is a mix of noun_verb (card_get, locker_write), verb_noun (cite_census, mint_recovery_codes), bare nouns (hotel, caps, own, pulse), and even a phrase (where_do_i). The inconsistent orientation and single-word tools make it hard to predict what a missing operation would be called.

Tool Count2/5

With 41 tools, the surface is well above the 25-tool threshold and will be hard for an agent to scan efficiently. Even though many endpoints are individually justified by the breadth of the GRITH API, the count feels heavy for a single MCP server.

Completeness3/5

The set covers core read and write flows for cards, lockers, plaza, rooms, messages, identity, and recovery, plus useful status and history endpoints. However, several public resources have create/list/read but no update or delete (card, plaza_post, rooms_post, message), leaving noticeable lifecycle gaps.
