Revokes the Open Finance consent for a specific bank and deletes the connection data. The bank's data will no longer be available. Returns an add_connection_url to re-connect if needed.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already set destructiveHint=true; the description adds clarity by stating data will no longer be available and mentions the return of an add_connection_url, providing extra behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two clear, front-loaded sentences with no extraneous information; every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Missing parameter explanation and lack of error handling or prerequisites for this destructive action; return value is mentioned but output schema is absent, leaving gaps in completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The sole parameter 'item' is not explained in the description or schema (0% coverage). The description mentions 'a specific bank' but fails to clarify that 'item' likely refers to an identifier.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool revokes consent and deletes connection data for a specific bank, distinguishing it from sibling tools like openfinance_list_connections or connect.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use when you need to disconnect a bank, but lacks explicit guidance on when not to use or alternatives like listing connections first.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clearly distinct purposes (e.g., force_sync vs get_item_status, list_accounts vs get_accounts_detail). Minor overlap exists between list_transactions and list_transactions_by_item, and between get_account_balance and list_accounts (which also contains balance), but descriptions clarify when each should be used.
All openfinance_* tools follow a consistent snake_case verb_noun pattern (list, get, force_sync, disconnect, update). The generic tools (authenticate, connect, marketplace, report_bug, show_version, toolkit_info) are also lowercase with underscores where needed, though they lack the openfinance prefix. No mixing of camelCase or chaotic patterns, so mostly consistent with minor deviation.
25 tools is on the heavy side for a single server, but justified given the breadth of Open Finance operations (accounts, transactions, bills, loans, investments, connections, categories, provider status). The count is borderline heavy but not excessive for the domain, though some consolidation could be possible (e.g., merging get_account_balance into list_accounts).
The tool surface covers the full lifecycle for financial data: listing, getting details, forcing syncs, disconnecting, updating categories, checking provider status, and handling investments/loans/bills. No obvious dead ends; even connection management includes search, connect URLs, and re-authentication flows. The set appears comprehensive for its intended purpose.
