Returns connection status and URLs. When all providers are connected, returns authenticated:true and empty pending[]. When credentials are missing, returns connect_url for the toolkit and per-install URLs.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, and destructiveHint. The description adds meaningful behavioral context beyond annotations by detailing the response structure for both connected and missing credentials scenarios. 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences with no fluff. It front-loads the core purpose and then elaborates with specific examples. Every sentence serves a clear function.
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?
Given no parameters and no output schema, the description fully covers what the tool does, including both success and failure cases. It is complete enough for an agent to understand the tool's behavior without additional context.
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?
There are zero parameters, so the baseline is 4. The description does not need to add parameter information; it correctly focuses on the function and output. Schema coverage is 100% with no parameters to document.
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 it returns connection status and URLs, and distinguishes two distinct states: all providers connected vs credentials missing. It uses specific language like 'returns', 'authenticated:true', and 'connect_url'. No confusion about what this tool does.
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 usage for checking overall connection status, but does not explicitly state when to use this tool versus sibling tools like 'authenticate' or 'openfinance_list_connections'. No when-not-to-use or alternative guidance is provided.
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 map clearly to a distinct openfinance resource or action (accounts, transactions, bills, investments, loans, connections, provider health), and the platform utilities are a separate family. The only realistically confusable pairs are openfinance_list_transactions vs openfinance_list_transactions_by_item and openfinance_list_accounts vs openfinance_get_accounts_detail, but the descriptions draw sharp boundaries between them.
The 19 openfinance_* tools follow a strong openfinance_<verb>_<noun> convention, with only minor exceptions like openfinance_provider_status and openfinance_list_transactions_by_item. The six platform tools mix bare verbs (authenticate, connect), nouns (marketplace, toolkit_info), and verb_noun (report_bug, show_version), but they are clearly a separate utility layer.
25 tools sits at the top of the 'feels heavy' band. The number is defensible for a full Open Finance data product plus platform management tools, but an agent is exposed to a lot of surface area, and the same server mixes a banking-data adapter with a marketplace/utility layer.
The openfinance surface covers the full lifecycle: search/connect/reconnect/disconnect banks, force-sync, item status, provider incidents, accounts, balances, transactions per account and per connection, credit-card bills with paid-status derivation, investments and investment transactions, loans, loan detail, and transaction categorization. Platform tools cover auth, connection status, toolkit state, version, bug reporting, and marketplace operations, so there are no obvious dead ends.
