Kerne Honesty Index MCP

A Model Context Protocol server that provides an hourly, signed board comparing advertised versus realized yield for stablecoin vaults. It allows agents to query the full board, individual rows with reproduction data, methodology, corrections, and right-of-reply slots, all derived from on-chain ERC-4626 share price growth.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Advertised versus realized yield for synthetic and yield-bearing dollars, measured from ERC-4626 share-price growth on chain and published as a signed hourly snapshot. Call list_rows, then get_row for the evidence behind a figure. Read get_methodology before comparing rows: a null gap means the two figures are not comparable, never that a protocol paid zero, and a protocol in an announced wind down paying nothing is behaving correctly. The board is published by Kerne Protocol, which is measured on it and lists its own row first by rule; get_board reports in summary.kerneIsWorst whether Kerne is currently the worst row, recomputed rather than claimed. get_methodology carries the one command that re-derives every figure from public chain data using a second implementation, so nothing here has to be taken on trust.

list_rows — List the rows on the Honesty Index
Advertised by the server during the last successful anonymous check.

The roster: every vault the Kerne Honesty Index measures, with its key, protocol, symbol, chain and contract address. Cheap. Call this first to find the key for get_row.

list_rows input schema
{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
get_board — Get the whole board
Advertised by the server during the last successful anonymous check.

The full Kerne Honesty Index: what each of the measured synthetic and yield-bearing dollars ADVERTISES against what its holders actually REALIZED, computed from ERC-4626 share-price growth on chain over a 30 day window, plus the board summary and the provenance of the snapshot. Kerne Protocol publishes this board, is on it, and lists its own row first by rule. A gap of null means the two figures are not comparable, never that the protocol paid zero.

get_board input schema
{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
get_row — Get one row in full
Advertised by the server during the last successful anonymous check.

One row with everything behind it: the verbatim advertised quote and the first-party page it was read from, the capture date, both block heights, both share prices, the arithmetic, the exact eth_call payloads needed to reproduce it, and any right of reply the protocol has published.

}
get_methodology — How the numbers are produced, and where the method stops being fair
Advertised by the server during the last successful anonymous check.

The measurement, the comparability rules that decide when a gap may be stated at all, the capture expiry, what this board deliberately does not cover, and the standing commitment if you reproduce a row and get a different answer.

get_methodology input schema
{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
get_corrections — The append-only corrections log
Advertised by the server during the last successful anonymous check.

Every time this board changed something it had stated about a named company, or changed a method rule, with the old value, the new one, the date and the rule that stops a repeat. Append only: entries are never edited or removed.

get_corrections input schema
{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
get_right_of_reply — The Right of Reply, and everything published under it
Advertised by the server during the last successful anonymous check.

The free, permanent, unedited reply slot every measured protocol has on its own row, its terms, the only three things that will not be published, and every reply received so far.

get_right_of_reply input schema
{
  "type": "object",
