RivalSearchMCP

You have access to 9 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

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
Need a unified entity profile in one shot? → research_topic --mode entity --topic "OpenAI"

Tool reference

For full flags, types, and defaults for each tool, read:

resources/search.md — web_search, social_search, news_aggregation, github_search, map_website
resources/content.md — content_operations, document_analysis
resources/research.md — research_topic, scientific_research

Output

All tools return structured text to stdout. Errors go to stderr. Exit codes: 0 success, 1 tool error, 2 connection failed.
