SeenRelay is an MCP server with 2 tools an agent can call, among them check_fact, observe_fact. It answers at https://seenrelay.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 23 October 2026, succeeded.
Avoid redundant expensive validation. CHECK recent evidence; OBSERVE fresh independent results.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_fact | Cost preflight before repeated paid or slow source-backed validation, especially across an agent fleet. Use before paid web search, metered scraping, browser/extraction, rate-limited APIs or multi-step validation when the caller already has Inputs: fact, known_value, max_age_seconds |
observe_fact | After independently performing a source-backed validation, deposit the observed result for later CHECKs. Returns accepted=true when a new observation is stored or deduplicated=true for a recognized retry/recent duplicate. Never OBSERVE hear Inputs: fact, value, observed_at, observer_id, observer_proof, evidence_fingerprint |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://seenrelay.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.ovladon. Endpoint host: seenrelay.com. ARD identifier: urn:air:io.github.ovladon:mcp:seenrelay.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
