api record

GROUNDTRUTH counts what actually happened to token launches on pump.fun and Robinhood Chain: outcome labels, liquidity histories, and the wallet networks around a creator. Start with groundtruth_scan_coin for one token, or groundtruth_screen_creator for everyone connected to a creator. Rates are only meaningful beside the chain baseline the tools return with them, and an empty result means not captured, not cleared. These tools return the counts and the verdict and impose no trading policy: Sentinel’s guardrails are Sentinel’s defaults, not this server’s. Your bot, your risk policy.

_ is it live, free and safe measured by this hub
Is groundtruth-mcp-server live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is groundtruth-mcp-server free to use?
Yes — the hub reached it with no key and no payment.
What tools does groundtruth-mcp-server have?
15 tools: groundtruth_time_to_rug, groundtruth_creator_replay, groundtruth_scan_coin, groundtruth_copycheck, groundtruth_kol_board, groundtruth_scoreboard, groundtruth_seal_call, groundtruth_scorecard, ….
Is groundtruth-mcp-server safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • groundtruth_autopsy_index open 1h ago

    Return the corpus-level figures the site publishes: launches captured per chain, how many resolved, and the share that rugged, died, survived or graduated, with the generation timestamp. This is market data GROUNDTRUTH has captured, not exhaustive coverage from a start date -- use it for baselines, not for totals of all activity.

  • groundtruth_time_to_rug unknown never probed

    WITHDRAWN 2026-09-29: the bands did not beat an age-matched baseline, so this now returns nulls plus band_withdrawn. Was: how fast coins in a given risk band actually rugged: median seconds from GROUNDTRUTH first seeing the curve to the rug, with p25 and p75, for one chain, band and window. Use it to answer "how long would I have had". The denominator is calls that rugged in the window AND carry a rug time, and it travels in the answer. Below 30 such calls the percentiles are null and enough_data is false -- say "not enough resolved calls to state a time" rather than quoting a number. Omit every argument to get the whole table in one call.

  • groundtruth_creator_replay unknown never probed

    What $100 would have done across a creator's last N resolved launches. Returns two rows. held_to_end is a MEASUREMENT: the recorded multiple at the end of each launch, with rugged launches counted as zero because the liquidity was pulled. clock_upper_bound is a CEILING, not a prediction: it uses the recorded PEAK multiple and only where the peak arrived at or before the band p25, because the published data carries the peak and the final multiple, not the path between them. Say "at most" when you quote it. Launches with no recorded multiple are excluded from BOTH the stake and the return, so the two describe the same set -- quote computed_for and of, never just the total. Solana only today: the Robinhood outcome data carries no peak multiple, so neither row can be computed there.

  • groundtruth_scan_coin unknown never probed

    What the KOL wallet launched, and how it ended. Rugged of resolved, seconds to the pull, every count with its N. One call. When the dev is on a KOL list, envelope.kol carries tag KOL / TOP PROFIT, the lists, yes-no flags and rank (never a name). Look up one token and return what GROUNDTRUTH counted about it: the outcome label (rugged, died, graduated, survived, or no outcome), liquidity and market-cap figures, holder counts, and the launch counts of the wallet that launched it. Accepts a Solana mint or a Robinhood Chain 0x contract address. This is the same read the public site performs when someone pastes a contract address. The answer carries the envelope; its live block holds the dev's last_mint_live, launched_live, bonded_live, mints_since_asof and ticker_asof (the newest mint the feed has seen). A dev WALLET pasted here answers not_token plus that dev's creator_record and the same live fields.

  • groundtruth_seal_call unknown never probed

    Stamp a verdict ahead of the outcome, so it can be counted later. This is the honesty mechanism: the row is hash-chained to the previous one under your API key, so a verdict cannot be edited or removed after the coin resolves. Stamp every call you make, including the ones you are confident about -- a scorecard built only from remembered wins is not a scorecard. Returns the row hash and sequence number.

  • groundtruth_scorecard unknown never probed

    How often calls stamped under this API key were right. Groups them by band and by what the coin actually did, resolved from the same data the card reads. A call whose coin has not resolved counts as PENDING, never as a win -- report pending alongside resolved, because the denominator is the point. Also returns whether the hash chain is intact; if it is not, say so rather than quoting the numbers.

  • groundtruth_screen_batch unknown never probed

Use this instead of calling groundtruth_screen_creator in a loop. known_bad is true only when the creator is in the published set, has at least 5 resolved launches, and rugs at 1.5 times the chain baseline or worse -- a bare rug rate is noise, the multiple is a decision. known_bad is null, NEVER false, for a creator not in our count: not in our count means nothing either way.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 8a84237d1a1426a5.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/8a84237d1a1426a5/claim. Over MCP: the claim_endpoint tool.
