GroundedKit MCP server
Which MCP servers are GroundedKit'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.

- Its tools do every use case we checked: trace a marketing stat back to its original source; have AI agents verify statistics before they cite them.
- Checked on 1 of the 7 days it takes to judge reliability.

- For "have AI agents verify statistics before they cite them", the likely first call is check_stat.
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 →
check_statPaste a marketing or influencer-marketing statistic (a sentence or a whole paragraph), or ask for a reference number (e.g. 'what share of US adults use TikTok'). Returns the best-matching checked claim with its verdict, confidence…
verify_textPaste a whole draft (up to 20,000 characters: a blog post, deck notes, an email, a social caption). Splits it into sentences, keeps each sentence that contains a number or statistic, and matches each one against the checked claims…
search_claimsKeyword search over all checked marketing statistics (claim text, common phrasing, origin publisher). Optionally filter by verdict. Returns short summaries; get_claim returns the full record for an id.
get_claimFull record for one checked claim by id (slug) or claim page URL: verdict, confidence, origin, exact quote, method and sample, drift, publisher interest, safe rephrasing and every source we opened.
list_verdictsThe four verdicts (verified, misquoted, outdated, unsourced) with definitions and how many claims carry each, plus confidence levels and dataset info.
How to connect
Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:
{
"mcpServers": {
"marketing-stats": {
"type": "http",
"url": "https://groundedkit.com/mcp"
}
}
}Add it
Claude Code, in a terminal
claude mcp add --transport http groundedkit https://groundedkit.com/mcpclaude.ai, ChatGPT and other clients: add https://groundedkit.com/mcp as a custom connector in the settings.
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.
