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

A4.4/5.0
Behavior4/5

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

Annotations already mark readOnlyHint, idempotentHint, destructiveHint. Description adds valuable context about reconnect_url behavior (UPDATE mode, non-destructive refresh) 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?

Single paragraph, reasonably concise. Every sentence adds value, though the reconnect_url explanation could be slightly more compact.

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?

No output schema, but description fully explains return fields (connector_id, item_id, bank name, URLs) and behaviors. Complete for a parameterless list 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?

No parameters (0 params, 100% schema coverage). Baseline is 4. Description does not need to add parameter details.

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?

Description clearly states it returns saved bank connections with specific fields (connector_id, item_id, bank name, reconnect_url, add_connection_url). Distinguishes from sibling list tools by focusing exclusively on connections.

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?

Explicitly explains when to use the reconnect_url (for re-authentication, MFA connectors, LOGIN_ERROR, stale data) and notes it does not consume a slot. Does not contrast with other list tools but context is clear.

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

Most openfinance_ tools target distinct resources (accounts, transactions, bills, loans, investments, connections, categories), so the core surface is clearly separated. However, several pairs could be confused at first glance: list_transactions vs list_transactions_by_item (both return transactions but at different scopes), get_credit_card_bill vs list_credit_card_bills (bill detail vs list of bills), and get_account_balance vs get_accounts_detail (balance snapshot vs full account object). The detailed descriptions help, but the overlap is nontrivial.

Naming Consistency4/5

The openfinance_* tools follow a consistent pattern (list_, get_, update_, search_, force_sync, provider_status, disconnect_bank), all using snake_case with a clear domain prefix. However, the general platform tools (authenticate, connect, marketplace, report_bug, show_version, toolkit_info) have no such prefix or consistent verb_noun pattern, mixing the convention. The finance subset is strong, but the overall set isn't uniform.

Tool Count3/5

At 25 tools, this is at the upper boundary of acceptable for a broad financial domain covering connections, accounts, transactions, credit cards, loans, investments, categories, and provider health. Each tool adds real capability, so it doesn't feel bloated, but it's heavier than typical and pushes the borderline between well-scoped and too many.

Completeness4/5

The surface covers the Open Finance lifecycle thoroughly: connection management (list, reconnect, force sync, disconnect, provider status), account/balance reads, transaction listing (with filters, pagination, rich detail), credit card bills (closed and open/debt), loans, investments, category management, and a connector search. Obvious gaps like a tool for creating connections are handled via widget URLs rather than an API call, so the coverage feels adequate. Minor gaps exist (e.g., no explicit tool for updating a connection's credentials beyond reconnect URLs), but nothing that would block core workflows.
