A4.5/5.0
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint, idempotentHint, destructiveHint. Description adds that it returns platform and adapter versions, providing specific behavioral context beyond safety hints.
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?
Single sentence, directly front-loaded with purpose, no unnecessary words. High efficiency.
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 zero-parameter, read-only tool with no output schema, the description fully covers what the tool does. No gaps.
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?
No parameters exist; baseline for 0 params is 4. Description adds no param info because none needed.
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?
Description specifies the verb 'Show' and the resource 'current MCP platform and adapter versions'. Among siblings, no other tool provides version information, so it is clearly differentiated.
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?
No explicit when-to-use or alternatives, but the simplicity and uniqueness of the tool make usage obvious. Lacks explicit context like 'check version before using other tools'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.2/5.0
Disambiguation5/5
Each openfinance_* tool targets a distinct resource (account, transaction, bill, loan, investment) with a clear action (get/list/update/force_sync). The administrative tools (connect, authenticate, report_bug) are clearly separate. No two tools appear to perform the same function.
Naming Consistency4/5
The openfinance_* tools follow a consistent verb_noun pattern (e.g., get_account_balance, list_transactions, update_transaction_category). Minor deviations like openfinance_provider_status (lacks a verb) and openfinance_force_sync (verb phrase) slightly break the pattern, but the overall convention is predictable.
Tool Count4/5
25 tools is on the higher end but appropriate for a comprehensive Open Finance server covering accounts, transactions, bills, loans, investments, connections, and administration. Each tool has a distinct purpose and none feel redundant.
Completeness5/5
The tool surface is complete for the domain: it covers connection management (connect/disconnect/force sync/status), account and transaction queries, credit card bills, loans, investments, and transaction categorization, plus admin utilities. No obvious gaps that would block typical workflows.
