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.

A4.9/5.0
Behavior5/5

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

Annotations already declare this as a safe read (readOnlyHint=true, destructiveHint=false). The description adds valuable behavioral context beyond annotations: the widget opens in UPDATE mode, data refreshes in place, and reconnect does not consume a slot. No contradictions 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.

Conciseness5/5

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

The description is three sentences, front-loaded with the primary function, followed by concise yet informative details about the URLs. Every sentence earns its place with no fluff or repetition.

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 having no output schema, the description sufficiently explains the return fields and the conditions for using the included URLs. It covers the tool's purpose, usage, and edge cases, making it fully adequate for an agent to select and invoke 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?

The tool has zero parameters, so the baseline is 4. The description doesn't need to explain parameter semantics; instead it clarifies the return payload, which is more relevant. No parameter documentation is required.

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 the tool returns saved bank connections with specific fields (connector_id, item_id, bank name, reconnect_url, add_connection_url), making it distinct from sibling tools that handle accounts, transactions, or disconnection. The verb 'Returns' is specific and the resource is well-defined.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly explains when to use the reconnect_url (re-authentication for MFA connectors, LOGIN_ERROR, stale non-Open-Finance data) and what add_connection_url is for, providing clear context and distinguishing between use cases. It also advises that reconnect does not consume a connection slot or require disconnecting first.

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

A4.1/5.0
Disambiguation4/5

Each Open Finance resource has a clearly named list/get pair, and connection status vs provider status vs force sync are distinct. The main ambiguity is between list_accounts (which already carries balances) and get_account_balance, and between list_transactions and list_transactions_by_item, which requires reading the descriptions carefully.

Naming Consistency4/5

The openfinance_* tools follow a consistent verb_noun pattern (list_*, get_*, update_*, force_sync, search_*). Exceptions like marketplace, toolkit_info, and openfinance_provider_status break the pattern slightly, but the two logical groups are predictable internally.

Tool Count3/5

At 25 tools this is on the heavy end of the scale. Most tools have a real purpose, but several list/get pairs and the multi-purpose marketplace mega-tool could be consolidated without losing functionality, making the overall surface feel larger than strictly necessary.

Completeness4/5

The Open Finance surface is impressively broad: connections, accounts, balances, transactions, credit-card bills, loans, investments, categorization, sync, provider health, and connector search are all covered. Minor gaps like a single-transaction getter or a consolidated statement export force agents to assemble data with extra calls, but no critical workflow is blocked.
