openfinance_provider_status

Read-onlyIdempotent

Checks the LIVE operational status of the Open Finance provider (its public status page) — this is the PROVIDER's health, separate from your own connection's openfinance_get_item_status. Use it whenever data looks incomplete or stale even though a connection shows UPDATED (accounts/transactions/balances missing, a bank not returning everything): it reveals an upstream outage or a known incident on a specific bank/connector, so you can tell a provider-side problem apart from a connection that just needs reconnecting. Returns the global indicator (none/minor/major/critical), degraded components, open incidents, and — when you have banks connected — flags the incidents that affect YOUR connected banks in your_banks_affected.

TDQS

A4.9/5.0
Behavior5/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true; description adds beyond by detailing the return value (global indicator, degraded components, incidents, your_banks_affected) and the live check nature. No 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?

Two sentences, front-loaded with the core purpose, then usage guidance and output details. No wasted words; every sentence adds value.

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 no parameters and no output schema, the description explains the output fields and usage context thoroughly. It provides enough for an agent to decide when to invoke and what to expect.

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 exist (schema has zero properties), so baseline is 4. Description adds no parameter info but schema coverage is trivially 100%.

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 it checks the LIVE operational status of the Open Finance provider, distinct from connection status. It uses specific verbs ('Checks') and resource ('Open Finance provider') and differentiates from sibling tool openfinance_get_item_status.

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?

Explicitly says when to use: 'whenever data looks incomplete or stale even though a connection shows UPDATED'. Also distinguishes from connection status tool and explains it helps differentiate provider-side problems from connection issues.

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

A4.2/5.0
Disambiguation4/5

Most tools have distinct purposes, especially with the openfinance_ prefix grouping banking operations. However, pairs like openfinance_list_accounts vs openfinance_get_accounts_detail and openfinance_get_credit_card_bill vs openfinance_list_credit_card_bills could cause minor confusion, though descriptions help.

Naming Consistency5/5

Tools consistently use snake_case with a clear verb_noun pattern. Open finance tools all start with openfinance_, and utility tools use simple verbs like authenticate, connect, report_bug. No mixing of conventions.

Tool Count3/5

At 24 tools, the count is on the higher side of the borderline range. The server combines platform management (6 tools) and banking operations (18 tools), which justifies the number, but it feels slightly heavy for a single server.

Completeness5/5

The tool surface covers all major banking operations (accounts, transactions, credit cards, investments, loans) and includes essential maintenance tools (sync, status, disconnect, search connectors). Platform management is also comprehensive with authentication, marketplace operations, and diagnostics.
