15 tools

• search_reading_sources

  Search a dated local index of exact public Markdown documents from four official publishers. Literal title/URL terms only, not semantic search. Returns ids, source URLs, listing provenance and pagination. A listing is not a successful reading test, new service, factual…

• run_discovery_workflow

  Preferred default for multi-step service discovery. One fixed read-only discovery workflow, inspired by Code Mode. Send requestJson containing mode recommend/catalogue, discoveryRequestJson with the exact original complete recommendation/search JSON string, optional…

• search_llm_providers

  Read dated official-documentation observations for LLM providers. Optional query uses literal metadata terms; planType distinguishes free-tier, evaluation, recurring-credit, trial-credit, paid-credit and unknown. All supplied filters are retained; unknown arguments are rejected…

• search_discovered_services

  Read the separate, automatically collected Official MCP Registry index. Send requestJson containing query, limit and offset. Literal substring matching over names, descriptions and registry names; no semantic translation or suitability assessment. These records are NOT…

• get_service_evidence

  Read the published evidence for one current service. Source review, observed provider response and internal task review are separate. Inspect observation dates, failures, scope and validity. Internal tests are not independent certification; failed-attempt timing is not a latency…

• find_service_alternatives

  Read-only alternatives. Send the original complete requestJson used for recommend_services and excludedProviders (1–20 distinct service slugs). Preserves all task, account, payment, protocol, budget and language conditions; never broadens a query or drops filters. A skipped…

• recommend_services

  Full standalone recommendation response. Prefer run_discovery_workflow when a shortlist with evidence, connection details or comparison is needed; use this tool for the full candidate/exclusion records. Read-only shortlist for an explicitly selected web_search, read_page…

• get_benchmark_suite

  Read 20 predefined public-documentation task cases across English, Turkish, German and Spanish, with source URLs and review rubrics. Five task families have four language variants; this is a test design, not 20 independently tested capabilities. The suite publishes no shared…

• plan_benchmark

  Plan a predefined benchmark case without running it. Read get_benchmark_suite for a caseId, then send requestJson containing {caseId,constraints?:{maxTaskCostUsd?,maxDurationMs?,requireMeasuredQuality?}}. Preserve every intended constraint inside requestJson; unknown and…

• search_services

  Find services using deterministic keywords, bounded language aliases and category/protocol/pricing filters. Prefer requestJson (at most 8192 UTF-16 code units): serialize the complete request as JSON in this single string to preserve every field through connectors. query and…

• get_service

  Read one full catalogue entry, including documentation links, pricing caveats and source check date. Does not connect to the provider.

• compare_services

  Retrieve 2–3 selected catalogue entries for comparison. Does not test providers or infer performance from their listing.

• get_connection_spec

  Read recorded endpoint, declared interfaces, authentication method, setup gaps and source evidence. Transport can come from matching Registry evidence or an exact-endpoint reviewed setup guide. Read the setupGuide option for client authentication and session steps. Unknown…

• get_connection_handoff

  Read a reviewed host-managed connection plan for Exa, Jina or Browserless. Only provider is accepted. Returns official endpoints, authentication method, setup steps, source evidence and account-check limitations. Configure credentials only in your agent host; ToolSkipper does…

• get_task_options

  Plan an optional keyless task without contacting a provider. Send requestJson containing only task (web_search, read_page, pdf_parse or browser_screenshot), input (public search text or URL), optional provider (auto, exa, tavily, jina-ai, firecrawl or browserless), optional…
