qveris

qveris is a skill for Cursor from QVerisAI/qveris-agent-toolkit. It costs 58 tokens per session (1,885 once invoked), scanned A, original, MIT.

A guide for finding and using third-party web APIs through QVeris, a service that catalogues API capabilities. An API is a way for software to request data or actions from another service.

In plain words
What is it for?
Use it to discover, inspect, test, and generate code for APIs that provide things such as weather data, stock prices, or public datasets.
Why use it?
It helps identify a suitable external service and check how to call it before writing integration code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qveris scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

When to use QVeris

Choose among connected tools and QVeris using task fit, data quality/freshness, cost, user constraints, and call overhead. Use QVeris when at least one of these is true:

  • the current environment lacks the required capability or live/structured data source;
  • the correct provider or API is not known in advance;
  • the task benefits from comparing providers on relevance, schema, quality, latency, or cost;
  • the preferred provider is unavailable or fails and a fallback is needed;
  • the user explicitly asks to discover or call a capability through QVeris.

Local computation and transformations do not need QVeris. For qualitative pages, tutorials, or factual browsing, use an available browsing tool unless structured API data or provider routing is required.

When external functionality is needed, follow this two-phase workflow. Discover, Inspect, Probe, and Call are independent protocol actions, not four mandatory steps.

Phase 1: Discover and Call Capabilities via MCP

  1. Identify what capability the user needs.
  2. Call discover with a functionality description (not parameter names). Request only a few results unless comparison is necessary.
  3. If the best discovery result already includes enough parameter guidance and cost information, call it directly with call, passing parameters via params_to_tool.
  4. Use inspect only when selection or valid request construction depends on contract details omitted by Discover, multiple candidates need comparison, or a host-managed metadata entry needs refreshing.
  5. Use probe only when parameters need validation, a current quote is needed for a budget decision, or the user explicitly wants a preflight. Probe is not a prerequisite for Call; its quote is not a price reservation or user authorization.
  6. Repeat or broaden the discovery query only if no suitable capability is found or a safe fallback is needed.

qveris is a skill published in the GitHub repository QVerisAI/qveris-agent-toolkit (261 stars, last pushed yesterday), licensed MIT. It adds 58 tokens to every session and 1,885 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
