BankConv MCP server

by wassim

Check the page balance

get_credits
Read-only

Check remaining BankConv page credits for the current period before converting large PDF batches, returned as read-only JSON.

Instructions

Check how many BankConv pages the account has left in the current period, as JSON. Each PDF page uses one page, so check before converting a large batch. Read-only.

TDQS

A3.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, so the trailing 'Read-only' is redundant with structured data. The description does add one genuinely useful behavioral fact — that each PDF page consumes one credit and the balance is scoped to the current period — but says nothing about what happens when the balance hits zero, when the period resets, or the response shape.

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?

Three short sentences, each carrying distinct information (what it returns, how credits are consumed, why it matters). The purpose is front-loaded and there is no filler beyond the redundant 'Read-only'.

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?

For a zero-parameter read with no output schema, the description covers what is being measured, the units, and the reason to call it. Only the JSON shape and exhausted-quota behavior are left implicit, which is minor.

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?

The tool takes zero parameters, so there is nothing to disambiguate; baseline 4 applies. The description cannot and need not add parameter detail.

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?

States a specific verb and resource (check remaining BankConv pages), the quota unit (one PDF page = one page), and the period scope (current period). It is clearly distinguishable from the sibling conversion/download tools, though it does not name them explicitly.

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

Usage Guidelines4/5

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

Gives a concrete usage trigger: check before converting a large batch, which implicitly routes the agent from convert_statement to this tool first. There are no explicit exclusions or named alternatives, but the decision context is clear.

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