Concurrent multi-engine web search across DuckDuckGo, Bing, Yahoo, Mojeek, and Wikipedia. Results are deduplicated and merged; failures on any single engine do not block the others.

Map and explore websites with different modes for different use cases.

One tool for every URL/content-level operation. Pick `operation`, provide whichever of `url`, `urls`, `content` that operation needs, and leave the rest defaulted. Parameter annotations above (visible in the MCP schema) state which operation each parameter applies to. Quick map of operation -> required inputs: retrieve url stream url analyze content extract url score urls (optionally metadata) find_conflicts urls (optionally claim) validate urls (≤100 URLs; checks liveness, redirects, paywalls, last-modified)

End-to-end deterministic research workflow. One tool, two modes: topic - open-ended search + fetch + extract entity - unified cross-source profile of a named entity Both modes auto-attach per-result quality scores and an aggregate confidence signal so callers can calibrate trust.

Scientific research tool for academic papers and datasets. Supports two operations: - academic_search: Search for academic papers across multiple sources - dataset_discovery: Discover datasets from various repositories Sources for academic_search (all keyless, queried concurrently): - openalex ~240M works, strong full-text search, OA-aware - crossref ~140M DOI-registered works (journals, books, conference proceedings, preprints) - arxiv physics/math/CS/stats/q-bio/q-fin preprints - pubmed NCBI biomedical index - europepmc biomedical + bioRxiv/medRxiv preprints Sources for dataset_discovery: - kaggle Kaggle datasets list endpoint - huggingface HuggingFace Hub datasets - zenodo CERN's open-science repository (CC-licensed) - dataverse Harvard Dataverse (largest research-data repo) Defaults pick the highest-recall combination per operation; pass `sources=[...]` to restrict.

Search across social platforms and communities for discussions and content. Supported platforms (no authentication required): - reddit Reddit (JSON API) - hackernews Hacker News (Algolia-powered full-text search) - devto Dev.to (tag lookup + recent-articles filter) - producthunt Product Hunt (RSS feed + client-side filter) - medium Medium (tag/topic RSS feeds + HTML fallback) - stackoverflow Stack Exchange (defaults to stackoverflow.com) - bluesky Bluesky public posts (AT Protocol) - lobsters Lobste.rs (HTML search + hot-feed fallback) - lemmy Lemmy federated posts (default instance: lemmy.world)

Aggregate news from multiple keyless sources concurrently. Sources queried in parallel (all verified working, no authentication required): - Google News RSS (search, with `when:` freshness operator) - Bing News RSS (search, with age filter; uses curl subprocess because Bing rejects httpx's TLS fingerprint) - The Guardian (full Content API via public "test" key) - GDELT 2.0 Doc API (global news index; may be rate-limited to one call per 5s per IP — gracefully skipped when throttled) - DuckDuckGo News (HTML scrape fallback) Results are deduplicated by URL and fuzzy title.

Search GitHub repositories without authentication. Searches public GitHub repositories using the public API. No authentication token required.

Download and analyze documents of multiple types with OCR support. Supports: PDF, Word (.docx), Text (.txt, .md), Images (.jpg, .png) with OCR. Extracts text content and metadata without requiring authentication. Automatically uses OCR for scanned PDFs and images.
