getPoolOHLCV

Read-onlyIdempotent

Get historical OHLCV candles (open, high, low, close, volume) for one pool over a time range, returned as a time-series array. Read-only and keyless. Use for 'price history of this pair', 'hourly chart for the last week', 'candles since Jan 1', or backtesting; for the single current price use getPoolDetails instead. Params: network (required); pool_address (required); start (required; easiest as a relative offset from now such as '-24h' or '-7d', so you need not know today's date; also Unix seconds, RFC3339 or yyyy-mm-dd); end (optional); interval one of '1m','5m','10m','15m','30m','1h','6h','12h','24h' (default '24h'); limit (default 100, max 1000 candles); inversed (optional bool, default false).

Input Schema

TableJSON Schema

Name	Required	Description	Default
`end`	No	OPTIONAL: End time for historical data, same formats as start (e.g. '-1h')
`limit`	No	OPTIONAL: Number of OHLCV data points to retrieve (default: 100, max: 1000). One row per `interval`.
`start`	Yes	REQUIRED: Start time. A relative offset from now is simplest and needs no knowledge of today's date: '-24h' (last 24 hours), '-7d', '-90m' (units s, m, h, d). Also accepts RFC3339 (e.g. '2024-01-01T00:00:00Z'), Unix epoch seconds and YYYY-MM-DD (treated as 00:00:00 UTC).
`network`	Yes	REQUIRED: Network ID from getNetworks (e.g., 'ethereum', 'solana')
`interval`	No	OPTIONAL: Interval granularity (default: '24h')	24h
`inversed`	No	OPTIONAL: Whether to invert the price ratio for alternative pair perspective (default: false)
`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.
`pool_address`	Yes	REQUIRED: Pool address or identifier

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so 'Read-only' is largely redundant. However, 'keyless' conveys an authorization fact the annotations do not (no API key required), and the stated default/max behavior (limit max 1000 candles, interval default '24h') adds operational context before invocation.

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-loaded with purpose, example phrasings, and the sibling alternative, then parameters. It is a single dense paragraph; the trailing parameter recap is somewhat redundant with a 100%-covered schema, but no sentence is filler.

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?

An output schema exists, so return-value detail is unnecessary, and the description covers scope, formats, defaults, required vs optional params, and the sibling boundary. Nothing an agent needs to call it correctly 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 every parameter, including the relative-offset format, the enum, and the limit default. The description's parameter recap largely restates schema content, adding little syntax or edge-case detail beyond it, which lands at the baseline 3.

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 historical OHLCV candles ... for one pool over a time range') plus the return shape ('time-series array'). It explicitly distinguishes itself from the sibling getPoolDetails ('for the single current price use getPoolDetails instead'), so an agent can route between them without opening either 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 concrete usage scenarios ('price history of this pair', 'hourly chart for the last week', 'candles since Jan 1', backtesting) and names the alternative tool for the contrasting case. The when-to-use condition is explicit, not inferred.

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