GROUNDTRUTH records 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 clean.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 11 tools

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_scoreboard unknown never probed
Return the public accuracy scoreboard: how many forward calls GROUNDTRUTH has made, how many have resolved, and how those resolved. Use this to judge how much weight to give the other tools.

mcp-tool
{ "type": "object", "properties": {} }
arguments 4 lines
groundtruth_autopsy_index unknown never probed
List the dated autopsies GROUNDTRUTH has published. Each is a writeup of one launch and what happened to it. Returns the available days; fetch a specific one from the public site at /autopsy/<day>.

mcp-tool
{ "type": "object", "properties": {} }
arguments 4 lines
groundtruth_scan_coin unknown never probed
Look up one token and return what GROUNDTRUTH recorded about it: the outcome label (rugged, died, graduated, survived, or no outcome recorded), liquidity and market-cap figures, holder counts, and the record 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.

mcp-tool
{ "type": "object", "required": [ "address" ], "properties": { "address": { "type": "string", "description": "A Solana mint (base58) or a Robinhood Chain contract address (0x...). Example: So11111111111111111111111111111111111111112" } } }
arguments 12 lines

groundtruth_screen_creator unknown never probed

Given one creator address, return every wallet that was early in that creator's launches: the role each played (creator, operator_pool, repeat_buyer, one_off), how many of this creator's launches it was early in versus how many it was early in anywhere, and that wallet operator's own rug rate. Also returns the apparent-versus-true collapse: how many wallets LOOK independent versus how many distinct actors they actually are, after merging wallets with near-identical launch histories. Rates come with the chain baseline, because a rate without its baseline is not a finding. This is the analysis no other source produces.

arguments 38 lines

groundtruth_screen_batch unknown never probed
Screen up to 200 creator addresses in ONE call and get one compact row each: launches, rug rate, the chain baseline, the multiple of that baseline, wallets tied, and the apparent-versus-true operator collapse. 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 we have no record of: absence is not innocence.

mcp-tool
{ "type": "object", "required": [ "creators" ], "properties": { "chain": { "enum": [ "solana", "rh" ], "type": "string", "default": "solana", "description": "Which chain these creators launched on." }, "creators": { "type": "array", "items": { "type": "string" }, "maxItems": 200, "description": "Creator addresses. base58 for Solana, 0x... for Robinhood Chain." } } }
arguments 25 lines
groundtruth_creator_flag unknown never probed
One creator in, one small answer out: is this creator known bad, with the rug rate, the chain baseline and the multiple that justifies the verdict. The cheapest call on this server -- use it when all you need is the decision rather than the wallet list. known_bad is null, never false, for a creator we have no record of. The data behind it is a batch export, so a creator who launched in the last hour is not in it yet; every response carries the timestamp it was generated.

mcp-tool
{ "type": "object", "required": [ "creator" ], "properties": { "chain": { "enum": [ "solana", "rh" ], "type": "string", "default": "solana", "description": "Which chain the creator launched on." }, "creator": { "type": "string", "description": "Creator address. base58 for Solana, 0x... for Robinhood Chain." } } }
arguments 21 lines
groundtruth_census_figures unknown never probed
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.

mcp-tool
{ "type": "object", "properties": {} }
arguments 4 lines
groundtruth_time_to_rug unknown never probed
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.

mcp-tool
{ "type": "object", "properties": { "band": { "enum": [ "RED", "AMBER", "GREEN" ], "type": "string", "description": "the band GROUNDTRUTH assigned at the time of the call" }, "chain": { "enum": [ "solana", "rh" ], "type": "string", "description": "solana (pump.fun) or rh (Robinhood Chain)" }, "window": { "enum": [ "24h", "7d", "30d" ], "type": "string", "description": "the resolution window; defaults to 24h" } } }
arguments 31 lines
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 record 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 record carries no peak multiple, so neither row can be computed there.

mcp-tool
{ "type": "object", "required": [ "creator" ], "properties": { "n": { "type": "integer", "description": "how many of the most recent resolved launches, 1-12, default 10" }, "usd": { "type": "number", "description": "the stake per launch in dollars, default 100" }, "creator": { "type": "string", "description": "the creator wallet (base58)" } } }
arguments 20 lines

groundtruth_seal_call unknown never probed

Seal a verdict BEFORE the outcome exists, so it can be scored 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. Seal 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.

arguments 36 lines

groundtruth_scorecard unknown never probed
How often calls sealed under this API key were right. Groups them by band and by what the coin actually did, resolved from the same record 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.

_ try it 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.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
