Read-onlyIdempotent

Search across ALL networks at once for tokens, pools, and DEXes by name, symbol, or address, returning three arrays: 'tokens', 'pools', and 'dexes'. Read-only and keyless. This is the cross-chain entry point when you do not yet know which network something lives on; once you have a network slug from the results, switch to the network-scoped tools. Use for 'find PEPE', 'what is the address for USDC', or 'which chain is this token on?'. Several words work: 'WETH USDC' returns the pools pairing both, and a network name ('brett base') narrows results to that chain. No matches returns empty arrays, not an error. Params: query (required; a name, symbol, or contract address, e.g. 'uniswap', 'bitcoin', or '0x...'); limit (optional, caps results per category, applied client-side).

Input Schema

Name	Required	Description
`limit`	No	OPTIONAL: Cap items returned per category (tokens, pools, dexes). Upstream returns all matches by default; this client-side slice keeps payloads small for agents. Applies independently to each category.
`query`	Yes	REQUIRED: Search term (e.g., 'uniswap', 'bitcoin', 'ethereum', 'WETH USDC', or a token address).
`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	Default
`dexes`	Yes
`pools`	Yes
`tokens`	Yes

A4.7/5.0

Behavior5/5

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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive. The description adds context beyond those: keyless operation, the exact return shape (three named arrays), client-side limit application, and the important no-match behavior (empty arrays rather than an error). This is meaningful behavioral disclosure.

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?

Front-loads scope and return shape, then routing guidance, then examples, then parameter summary. Every sentence adds distinct value; the multi-word query semantics ('WETH USDC', 'brett base') are non-obvious and earn their space.

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?

For a cross-chain search tool with an output schema and full annotation coverage, the description supplies everything an agent needs: scope, routing, return shape, empty-result semantics, and multi-token query behavior. Nothing material is missing.

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%, so the schema already documents query, its examples, and limit's client-side behavior. The description mirrors some of that but adds no syntax or format details absent from the schema, and it omits the required rationale parameter entirely. Baseline 3 is appropriate when the schema does the heavy lifting.

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 ('Search'), resource ('tokens, pools, and DEXes'), and scope ('across ALL networks at once'), and explicitly contrasts itself with network-scoped sibling tools. An agent can distinguish it from getTokenDetails or getNetworkPools without opening any 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?

Explicitly names the situation to use it ('when you do not yet know which network something lives on') and the transition condition to alternatives ('once you have a network slug ... switch to the network-scoped tools'). Provides concrete example queries that map real user intents to this tool.

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