MCP server exposing 8 Tavily tools (web search, fetch, crawl, map, QnA, context, and deep research) via Streamable HTTP for AI assistants to perform live web retrieval and research.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.
How we verified
Verified is a snapshot. Live keeps it current, and builds your track record.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
8/8 tools missing one or more hints — web_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); web_fetch (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); web_crawl (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
