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.

A4.7/5.0
Behavior5/5

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

The description discloses behavioral traits beyond the annotations: it explains the reconnect_url behavior (reopens widget in UPDATE mode for existing connections) and states that no connection slot is consumed and no disconnection is needed. Annotations already indicate readOnlyHint, idempotentHint, destructiveHint, so the description adds valuable context without contradiction.

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 concise (three sentences) and front-loaded with the most important information (what is returned). Every sentence adds value: the first states the output, the second explains the reconnect_url, and the third clarifies usage constraints.

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?

Given the absence of an output schema, the description adequately explains the returned fields and the crucial reconnect_url behavior. It covers all necessary aspects for an AI agent to understand and correctly invoke the tool.

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, so schema coverage is 100%. The description does not need to add parameter details; it provides full context about what the tool returns. Baseline of 4 is appropriate for zero parameters.

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 from sibling tools like openfinance_list_accounts by focusing on connections rather than accounts or transactions.

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 explicit guidance on when to use the reconnect_url for re-authentication needs (MFA connectors, LOGIN_ERROR, stale data) and clarifies that it does not consume a connection slot or require disconnecting first. However, it does not explicitly state when to use the main list functionality versus alternatives, but the list's basic purpose is clear.

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

A3.9/5.0
Disambiguation4/5

The openfinance_* family is cleanly separated by resource and action, and tricky pairs like list_accounts vs get_account_balance and list_transactions vs list_transactions_by_item are explicitly cross-referenced in descriptions. However, marketplace bundles a large set of sub-actions, and connect/toolkit_info partially overlap on reporting connection state, so a couple of boundaries are fuzzy.

Naming Consistency4/5

The openfinance_* tools consistently follow a verb_resource pattern with snake_case, which is highly predictable. The generic platform tools mostly fit the same style, but marketplace and toolkit_info are noun-only names, and openfinance_provider_status also breaks the verb pattern, so it is not perfectly uniform.

Tool Count3/5

At 25 tools, this server falls at the heavy end of the borderline range. The many openfinance_* list/get tools are individually justified for the financial domain, but adding platform tools like marketplace, connect, toolkit_info, and show_version makes the overall surface larger than a minimal server needs.

Completeness5/5

The financial surface is remarkably thorough: accounts, transactions, credit card bills, loans, investments, categories, connection lifecycle, sync, and provider health are all covered with list/get and update paths where applicable. The platform side also covers auth, connection status, marketplace discovery/execution, versioning, and bug reporting, leaving no obvious dead ends.
