Claimora MCP server
Which MCP servers are Claimora's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

The registry name sits under claimora.si. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

- Whether its tools do the product's job has not been judged yet.
Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look
None of the five warning signs in these definitions.
A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →
query_claimsSearch claim statements and excerpts. A domain keeps claims whose primary domain is that value or one of its aliases, such as cs.LG for ai-ml. Hits are ordered by keyword overlap, then a domain match, then evidence strength. cross_domain…
get_evidenceProvenance for one claim. Excerpts are short unless full_text is true. Use this after a search when you have a claim id and need the papers behind it. Example: get_evidence(claim_id="claim-attention"). Example…
get_contradictionsList claims stored as contradicting one claim. Returns each opposing claim id, status, evidence strength, and opposition strength. Example: get_contradictions(claim_id="<id from query_claims>").
get_updatesList claims whose last_updated is at or after a timestamp. Use this to read claims that changed after a time you already checked. Returns claim id, status, evidence strength, a shortened excerpt, and source_url when a paper link is known…
get_innovation_flagsList innovation flags, strongest first. Use this when you want links between claims rather than the claims themselves. Every flag includes flag_type and summary. summary is the short reason to follow the pair or skip it. flag_type is…
search_smartFind claims from a natural-language question. A question is matched on its content phrases. When that match is empty, the longest content terms are searched as keywords. Those hits stay on strategy question, set fallback to keyword, and…
get_authorsList authors linked to one claim. Use this when you have a claim id and need the people linked to it. Returns author id, name, and orcid. The list is empty when none are linked. Example: get_authors(claim_id="claim-attention"). Example…
query_lawList law records for one jurisdiction and area of law. Use this when you want jurisdiction-scoped records. Omitting jurisdiction returns science claims. Returns record id, status, evidence strength, a shortened excerpt, jurisdiction, and…
How to connect
Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:
{
"mcpServers": {
"claimora": {
"type": "http",
"url": "https://claimora.si/mcp"
}

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
