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
Behavior5/5

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

The description adds significant behavioral details beyond annotations (readOnlyHint, idempotentHint, destructiveHint). It explains that the reconnect_url opens the widget in UPDATE mode for existing connections, does not consume a slot, and does not require disconnecting first. No contradiction with 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 a single paragraph that efficiently conveys all key information. It could be split into shorter sentences, but it is not overly verbose and every sentence adds value.

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?

With no output schema, the description adequately covers the return fields and the important behavior of reconnect_url. It might lack details on error cases or pagination, but for a parameterless list command, it is sufficiently complete.

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 input schema has zero parameters and 100% coverage, so the baseline is 4. The description adds meaning about the output fields but cannot add parameter information since none exist.

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 that the tool returns saved bank connections with specific fields (connector_id, item_id, bank name, reconnect_url, add_connection_url). It distinguishes itself from sibling tools that handle authentication, disconnection, or sync operations.

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 explains when to use the returned reconnect_url (for re-authentication, MFA connectors, LOGIN_ERROR, stale data) and notes it doesn't consume a connection slot. While it doesn't explicitly compare to alternatives, the context is sufficient for an agent to decide when listing is appropriate.

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
Disambiguation4/5

Most tools have distinct purposes, especially with the openfinance_ prefix grouping banking operations. However, pairs like openfinance_list_accounts vs openfinance_get_accounts_detail and openfinance_get_credit_card_bill vs openfinance_list_credit_card_bills could cause minor confusion, though descriptions help.

Naming Consistency5/5

Tools consistently use snake_case with a clear verb_noun pattern. Open finance tools all start with openfinance_, and utility tools use simple verbs like authenticate, connect, report_bug. No mixing of conventions.

Tool Count3/5

At 24 tools, the count is on the higher side of the borderline range. The server combines platform management (6 tools) and banking operations (18 tools), which justifies the number, but it feels slightly heavy for a single server.

Completeness5/5

The tool surface covers all major banking operations (accounts, transactions, credit cards, investments, loans) and includes essential maintenance tools (sync, status, disconnect, search connectors). Platform management is also comprehensive with authentication, marketplace operations, and diagnostics.
