rival-search-mcp
Deterministic deep research via RivalSearchMCP. 10 tools: 5-engine web search (DuckDuckGo/Bing/Yahoo/Mojeek/Wikipedia), 9-platform social search (Reddit/HN/StackOverflow/Dev.to/Medium/ProductHunt/Bluesky/Lobste.rs/Lemmy), 5-source news (Google/Bing/Guardian/GDELT/DDG), 5 academic
What it does
RivalSearchMCP
You have access to 10 research tools via the CLI at scripts/cli.py. Run all commands with uv run scripts/cli.py.
Every tool returns deterministic, auditable output. There is no in-server LLM — you're the one doing the synthesis.
How to invoke tools
uv run scripts/cli.py call-tool <tool_name> --flag value
Available tools
web_search— concurrent search across DuckDuckGo, Bing, Yahoo, Mojeek, Wikipedia.

Use for community discussions.news_aggregation— Google News, Bing News, The Guardian, GDELT, DuckDuckGo News. Use for current events. Accepts--time-range day|week|month|anytime.github_search— search public GitHub repos. Use for code, libraries, projects.map_website— crawl a site inresearch/docs/mapmode. Use to explore site structure or documentation.content_operations— one tool, six ops (retrieve,stream,analyze,extract,score,find_conflicts). Use to get full page content, rate source quality, or surface disagreements between sources.document_analysis— extract text from PDFs, Word docs, images (image OCR via EasyOCR). Use for document processing.research_topic— two modes:topic(search + fetch + findings) andentity(fan out to 8 sources for a unified profile). Pass--session-idto auto-save findings.scientific_research— OpenAlex, CrossRef, arXiv, PubMed, Europe PMC (papers) + Kaggle, HuggingFace, Dataverse, Zenodo (datasets).research_memory— persistent workspaces withstart/add/get/list/delete. Use to iterate research across calls.
When to chain tools
- Found a URL from search? →
content_operations --operation retrieve --url <url> - Want to assess source trust before using results? →
content_operations --operation score --urls '[…]' - Two sources seem to disagree? →
content_operations --operation find_conflicts --urls '[…]' - Found a PDF link? →
document_analysis --url <url> - Need to explore a website? →
map_website --url <url> --mode docs - Doing iterative research? →
research_memory --operation start --topic "..."once, then pass--session-idtoresearch_topicon every call. - Need a unified entity profile in one shot? →
research_topic --mode entity --topic "OpenAI"
