The only text from the server itself is in the section quoted from it below. ## How to reach it - The client starts it as a local process (stdio): `npx -y [email protected]`. - Your MCP client knows it as `evernode` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__evernode__<tool>`. - No credentials. ## Tools 12 tools.

check_contract_apitestedHeuristic static check that a HotPocket Node.js contract uses the contract API correctly: an hpc.init(...) entry point, reading ctx (users / lclSeqNo), persisting ONLY through the consensused state mechanism (no arbitrary fs writes to non-state paths), handling ctx.users I/O, using ctx.lclSeqNo for time (not Date.now), and awaiting async consensus ops. Severity-rated with fix + why. Sibling to check_determinism — guidance, NOT a proof.Heuristic static check that a HotPocket Node.js contract uses the contract API correctly: an hpc.init(...) entry point, reading ctx (users / lclSeqNo), persisting ONLY through the consensused state mechanism (no arbitrary fs writes to non-state paths), handling ctx.users I/O, using ctx.lclSeqNo for time (not Date.now), and awaiting async consensus ops.
