JPYC Commerce MCP (ackey-web/JPYC-commerce-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.

JPYC Commerce MCP

Enables autonomous AI agents to conduct non-custodial commerce using JPYC stablecoin on Polygon, with trust scoring, task evaluation, negotiation, and on-chain verification via Soulbound Tokens.

Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

// key findings
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.

You'll be asked for 6 credentials: ANTHROPIC_API_KEY, DEPLOYER_PRIVATE_KEY, POLYGONSCAN_API_KEY, PRIVATE_KEY, RELAYER_API_KEY, RELAYER_PRIVATE_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

Tool annotations

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

19/19 tools missing one or more hints — get_sbt_profile (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); evaluate_task (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); propose_negotiation (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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 handlers catch errors

Only 0/19 tool handlers wrap calls in try/catch (0%)

Wrap each tool handler body in try/catch and return a structured error response.

Tool test coverage

Only 3/19 tools referenced in tests (16%)

Write tests that reference each tool by name so every tool has at least one test.

Production dependencies are patched

1 medium severity in production deps

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dependency freshness

1/7 production deps stale: keccak256@2022-05-07 (4.1y)

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
