How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
Returns a JSON audit result indicating whether the submitted tool facts match the reference facts, highlighting any permission scope drift, undeclared destructive actions, schema mismatches, or policy violations. Typically includes a compliance verdict, a list of specific discrepancies found, and severity indicators for each flag.
Example use cases
Catch silent permission scope expansion
“I need to audit our 'SendEmail' MCP tool — its current declared scope is 'read:contacts write:email delete:email' but the reference version only had 'read:contacts write:email'. The tool description says 'sends and manages emails', the paid operation is 'delivers email via SMTP', and no destructive action was declared. Check if this scope expansion is a problem.”
Validate new tool before deployment
“Before we deploy this new MCP tool called 'QueryLedger', can you audit it? Its description is 'queries blockchain transaction history', input schema accepts wallet_address and date_range, declared permission scope is 'read:ledger', paid operation description is 'returns paginated tx history', and destructive_action_declared is false. Compare it against the approved reference spec and tell me if everything checks out.”
Policy compliance check for agent marketplace
“We're listing a tool called 'RevokeAccess' on our agent marketplace — its declared scope is 'write:permissions', paid operation is 'removes user access tokens', and destructive_action_declared is false. Audit this against our policy that any tool with write:permissions must declare destructive actions, and flag any violations.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-mcp-paid-tool-permission-scope-auditorWhen to prefer
Choose this endpoint when you need to programmatically verify that an MCP tool's declared permission scope has not drifted from a known-good reference state, especially in agentic pipelines where tool definitions could be tampered with or silently updated. It is particularly valuable for marketplace operators, agent orchestrators, or security-conscious deployments that need continuous compliance validation of paid MCP tools before execution.
Side effects
- Missing required fields in facts or reference_facts objects returns a validation error
- Mismatched schema structure between facts and reference_facts may cause incomplete diff results
- Payment failure via x402 returns 402 with payment details before audit is performed
- Overly large input schemas (beyond 50 properties) are rejected by schema constraints
- Ambiguous or truncated tool descriptions may reduce audit accuracy
