SAP Chart Volume Profile

sap_chart_volume_profile

Compute volume profile (POC, VAH, VAL) for any Solana token using DexScreener price and volume data. Returns point of control, value area high/low, and bucket distribution. Read-only — uses free DexScreener REST API + local computation.

SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: priced by hosted x402 challenge. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`mint`	Yes	Token mint address (base58) to compute volume profile for.
`buckets`	No	Number of price buckets (default 20).

Output Schema

Name	Required	Description	Default
`content`	Yes	MCP content blocks returned to the caller.
`isError`	No	True when the tool result represents an application-level error.

B3/5.0

Behavior1/5

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

The description claims 'Read-only' but annotations set readOnlyHint: false, creating a direct contradiction. This undermines trust and confuses the agent about whether the tool modifies state. No further behavioral traits are disclosed beyond the misleading read-only claim.

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?

The core purpose is stated concisely in the first sentence. The second block of SAP execution guidance is somewhat lengthy but essential for the ecosystem, and the overall description remains front-loaded with the key information.

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

Completeness3/5

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

Given the tool's simplicity (2 parameters, read-only nature), the description provides adequate context for usage, including output types and data source. However, the contradiction with annotations and lack of usage guidelines detract from completeness.

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 parameters (mint and buckets) are already well-documented in the schema. The description adds marginal context about data sources (DexScreener) but does not elaborate on parameter constraints or usage beyond what the schema provides.

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?

The description clearly states the verb 'Compute volume profile', the resource 'any Solana token', and the outputs 'POC, VAH, VAL, and bucket distribution'. It distinguishes itself from sibling chart tools (e.g., sap_chart_indicators) by focusing specifically on volume profile computation.

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

Usage Guidelines2/5

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

The description does not explicitly state when to use this tool versus alternatives like sap_chart_indicators or sap_chart_ohlc. It only mentions 'any Solana token' but provides no comparative guidance or context for selection.

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