getCapabilities

Read-onlyIdempotent

Get the static agent onboarding guide for this server: supported workflows, network name synonyms (mapping words like 'eth' to the canonical slug 'ethereum'), recommended call sequences, and common pitfalls. Read-only and keyless. Read it once at the start of a session before your first query, or when asked 'how do I use this API?', 'what order should I call things in?', or 'which slug maps to eth?'. This returns onboarding docs, not live market data; for the actual list of network slugs use getNetworks, and for coverage totals use getStats. Takes no parameters beyond a short rationale.

Input Schema

Name	Required	Description	Default
`rationale`	Yes	REQUIRED. 1-2 sentence rationale for this call (e.g. "User asked for X; calling Y to fetch Z"). Logged for MCP improvement, never shown to end users. No PII or secrets. See the server `instructions` field for the full convention and worked examples.

Output Schema

Name	Required	Description
`stats`	Yes
`server`	Yes
`workflows`	Yes	Named tool sequences for common agent tasks.
`rate_limits`	No	How limits work for hosted tool calls. Not the REST allowances: your own plan does not apply, except to own_key_tools.
`agent_skills`	Yes
`documentation`	Yes
`common_pitfalls`	Yes	Known edge cases agents should be aware of.
`network_synonyms`	Yes	Canonical network id -> common alternates an agent might try.

First observedJul 28, 2026

TDQS

A4.6/5.0

Behavior4/5

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

Annotations already cover readOnly/idempotent/non-destructive, and the description still adds real context: "keyless" (no auth needed) and the explicit content boundary that it returns onboarding docs, not live market data. It does not mention caching or rate limits, but for a static doc endpoint that is a minor omission.

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

Conciseness4/5

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

Front-loads the resource and its contents, then usage timing, then exclusions — a sensible order with no filler sentences. It is on the long side with multiple quoted example phrasings, but each line carries routing or context value.

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

Completeness5/5

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

With an output schema present, return-value detail is not required, and the description still tells the agent the shape of the content and what it is not. Purpose, timing, auth profile, and sibling alternatives are all covered for a single-parameter tool.

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

Parameters4/5

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

Schema description coverage is 100% and the rationale parameter is fully documented in the schema, including length bounds and PII rules. The description only notes "takes no parameters beyond a short rationale," which correctly signals to the agent that there is nothing substantive to configure.

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

Purpose5/5

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

States a specific verb and resource ("Get the static agent onboarding guide for this server") and enumerates its contents: workflows, slug synonyms, call sequences, pitfalls. It also explicitly distinguishes itself from getNetworks and getStats, so an agent can separate it from the ~19 siblings without opening a schema.

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

Usage Guidelines5/5

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

Gives explicit timing ("once at the start of a session before your first query") and names the exact user phrasings that should trigger it. It also routes elsewhere for adjacent needs (getNetworks for slug lists, getStats for coverage totals), which is textbook alternative guidance.

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