EVIDIQ Cadence (evidiq/evidiq-cadence-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
An MCP server for durable, attested future execution, letting agents schedule one-shot, recurring, retry, and monitoring tasks with signed receipts and x402 payment.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
18/18 tools missing one or more hints — cadence_capabilities (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); estimate_cost (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); validate_schedule (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
16/18 tool handlers declare input schemas (89%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
12/18 tool handlers wrap calls in try/catch (67%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests pass
npm test failed — tests do not pass
Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.
Shell command execution
3 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
