Agent-readiness: C (70/100)

grade C

C (70/100): 0 error(s), 5 warning(s) across 10 tool(s); ~1,336 tokens of tool definitions.

Scores higher than 4% of 15,680 MCP servers Glimind has audited.

Its tool list costs an agent ~1,336 tokens per session — lighter than 65% of servers.

What to fix (6)

10 of 10 tool(s) carry no readOnlyHint/destructiveHint annotations.

Annotate read-only tools with {"readOnlyHint": true}. Agents and gateways can then run them without a confirmation prompt, and route around destructive ones. How to fix →

Tools: account, call_service, create_account, create_owner_key, create_topup_link and 5 more

4 tool(s) look like they change state (create/send/delete/pay…) but declare no destructiveHint.

Set annotations {"readOnlyHint": false, "destructiveHint": true|false, "idempotentHint": …}. Clients use these to ask the user before a side effect and to auto-approve safe reads. How to fix →

Tools: create_account, create_owner_key, create_topup_link, set_limits

3 parameter(s) across 3 tool(s) have no description.

Add a "description" to each parameter with its format and an example ("ISO 8601 date, e.g. 2026-10-17"). This is the commonest cause of wrong arguments on the first call. How to fix →

Tools: call_service, get_service, get_service_history

1 tool(s) have parameters with no type (no type/enum/anyOf/$ref).

Give every parameter a "type" (or "enum"/"anyOf"). Untyped parameters make models guess — strings for numbers, objects for arrays. How to fix →

Tools: call_service

Reachable 98.2% of the time over the last 30 days; median recovery 7 min.

Agents fail over to an alternative the first time a call fails. Add health checks and restart-on-failure, and avoid cold starts on serverless hosts.

No tool declares an outputSchema.

Declare outputSchema and return structuredContent (MCP 2025-06-18+). Agents can then parse results without guessing, and chain tools reliably. How to fix →

Auto-fix: 9 corrected tool definitions

Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. 3 tool(s) still need parameter descriptions written by someone who knows the API. All of them as JSON: /v1/readiness/mcp-registry%2Fsh.graded%2Fgraded-x402/fixes

call_service 1 change

create_owner_key 1 change

{
  "name": "create_owner_key",
  "description": "One-time: mint a separate OWNER key (gwo_…) for the human supervisor.

FAQ

Is the Graded X402 MCP server down right now?

How many tools does Graded X402 MCP server provide?

Graded X402 MCP server advertises 10 tools, including account, call_service, create_account, create_owner_key, create_topup_link.

How do I install Graded X402 MCP server?

Point your MCP client at this streamable-http endpoint: https://graded.sh/mcp

Is the Graded X402 MCP server safe to connect to an AI agent?

Glimind scanned all 10 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
