openfinance_get_loan_detail

Read-onlyIdempotent

Returns full loan contract detail by id (GET /loans/:loanId): interestRates[] (taxType, ratePercentage, indexer), contractedFinanceCharges[], balloonPayments[], warranties[], installments schedule (installmentsCount, paidInstallments, numberOfInstallmentsRemaining, installmentFrequency), amortizationScheduled, CET, ipocCode and dates. Use after openfinance_list_loans to deep-dive on a specific contract. Pass loan_ids as an array (1-50). { results, errors } batch shape.

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so safety is known. The description adds that it is a GET endpoint, returns specific fields, and returns a batch shape with results and errors, which is valuable beyond annotations.

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 description is two sentences: one listing fields, one for usage. It is efficient and front-loaded with the main action. Could be slightly more structured, but no unnecessary words.

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?

With no output schema, the description explains the return fields and batch shape. It covers purpose, parameter constraints, and usage sequence. For a simple tool with one parameter, it is complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter, loan_ids, has no description in schema (schema description coverage 0%). The description adds crucial meaning: it must be an array of strings with 1-50 items. This compensates fully for the missing schema documentation.

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 it returns full loan contract detail by ID, listing specific fields. It distinguishes itself from the sibling tool 'openfinance_list_loans' by advising use after listing loans for deep-dive.

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?

The description gives clear usage context: use after openfinance_list_loans. It specifies the parameter format (array of 1-50 loan_ids) and the batch shape. Does not explicitly state when not to use, but the context is sufficient.

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

A4/5.0
Disambiguation4/5

The tools are mostly distinct, covering authentication, marketplace navigation, Open Finance data retrieval (accounts, transactions, bills, loans, investments), and status/connector management. Some overlap exists between openfinance_list_transactions and openfinance_list_transactions_by_item (both return transactions, but the latter is a consolidated summary), which could cause momentary confusion, though descriptions clearly differentiate them.

Naming Consistency4/5

Tool names follow a clear pattern: 'openfinance_' prefix for Open Finance operations, with consistent verb_noun structure (list_accounts, get_account_balance, update_transaction_category). However, there are a few outliers like 'authenticate', 'connect', 'marketplace', 'report_bug', and 'show_version' that don't follow the Open Finance naming convention, though they serve different purposes and are still readable.

Tool Count4/5

With 25 tools, the count is slightly high but justifiable given the broad scope: the server covers Open Finance banking data (accounts, transactions, bills, loans, investments, connections), marketplace operations, and system utilities. Not all tools are used in every session, but each serves a distinct purpose, and the count remains manageable due to clear grouping.

Completeness4/5

The tool surface covers the core Open Finance lifecycle well: list and get accounts, transactions, bills, loans, investments, plus sync, reconnect, and category updates. It also includes connector search and provider status. Minor gaps exist, such as no explicit tool for updating or deleting a transaction category rule, and no direct CRUD for connections (only list and disconnect), but these are acceptable gaps.
