Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
HONESTY_MCP_ENABLE_CODE_EXECOptional | Set to exactly 1 to turn on the tools and inputs that run JavaScript sent by the calling agent (check_payout_invariance runtime mode, check_mutation_invariance, compute_divergence's groupBySource). Off by default; any other value leaves them off. Turning it on is not a sandbox: the code runs with t… |
HONESTY_MCP_WORKER_TIMEOUT_MSOptional | Timeout in milliseconds for the worker thread (a time limit, not a sandbox) that runs caller-supplied JS source (check_payout_invariance runtime mode, check_mutation_invariance, compute_divergence's groupBySource). Defaults to 10000. |
