Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| corroborate_claim | Given a factual/news claim, returns how INDEPENDENTLY it is being reported. Use before relying on a current-event claim. Output: verdict (CONFIRMED = 2+ independent origins | SINGLE_SOURCE | UNCORROBORATED), count of independent story origins (wire/syndication echoes collapse to one), per-source evidence (outlet, domain, url, date), confidence 0-1, coverage flag, honest caveats. Measures REPORTING corroboration, not truth — no stance detection, so a distorted claim about a real event may still show coverage; verify specifics against the returned sources. Keyless, read-only, deterministic; if all sources are unreachable it errors rather than returning a false negative. |
| find_sourcesA | Multi-engine news/source search (Google News, GDELT, Hacker News) for a query: a deduped list of {outlet, domain, url, date}. Use when you want raw coverage to judge yourself, not a scored verdict — the cheaper primitive under corroborate_claim. Keyless, read-only. |

Scored across 1 tool
With only one tool, there is no possibility of ambiguity. The single tool has a clear purpose and cannot be confused with others.
The tool name 'find_sources' follows a consistent verb_noun pattern, and since there is only one tool, there is no inconsistency.
A single tool, 'find_sources', feels too few for a server named 'corroborate-mcp', which implies a broader scope including claim verification. The tool is described as a 'cheaper primitive', suggesting that a more complex tool ('corroborate_claim') is missing, making the count inappropriate.
The server's purpose appears to be corroboration, but it only provides a news search tool. The description explicitly references a missing 'corroborate_claim' primitive, leaving a significant gap. There are no tools for actual claim verification, making the surface severely incomplete.
