openfinance_list_connections

Read-onlyIdempotent

Returns the saved bank connections for this install: connector_id, item_id, bank name, a per-connection reconnect_url, and an add_connection_url to link additional banks via the Open Finance widget. The reconnect_url reopens the widget in UPDATE mode for that EXISTING connection (user re-enters credentials / MFA token and the data refreshes in place) — use it when a connection needs re-authentication (MFA connectors, LOGIN_ERROR, stale non-Open-Finance data). It does NOT consume a connection slot and does NOT require disconnecting first.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already indicate read-only and non-destructive behavior. The description adds valuable details about the reconnect_url's behavior (update mode, no slot consumption) that go 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.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core purpose and then elaborating on a key feature. Every sentence is informative and concise.

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?

Despite no output schema, the description fully covers the returned fields and special behaviors. With zero parameters, it provides all necessary context for an agent to use the tool correctly.

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?

There are no parameters, and schema description coverage is 100% (trivially). The baseline for 0 parameters is 4, and the description adds no parameter-specific information, which is appropriate.

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 saved bank connections and lists specific fields. It distinguishes itself from siblings by mentioning unique elements like reconnect_url and add_connection_url, making the tool's purpose unambiguous.

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 provides guidance on using the reconnect_url for re-authentication scenarios, but does not explicitly compare to sibling tools. However, the context of listing connections is clear, and the reconnect use case is well explained.

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.
