Tools (28)

`artifact.integrity_manifest`	PAID $0.10 USDC on Base via x402. Creates deterministic SHA-256 entries and a root manifest hash for supplied text artifacts. Calling this MCP tool does not spend funds; it returns the exact PAYMENT-REQUIRED challenge and canonical paid execution endpoint.
`capability.get`read-only	FREE. Use name for legacy deterministic capability metadata or capabilityId for public marketplace metadata, rights and provenance.
`capability.search`read-only	FREE MARKETPLACE FILTERED DISCOVERY ONLY. Search active public marketplace capabilities when one or more filters are known: text, category, provider, delivery type, or price. Metadata is free; purchased execution and deliverables are not. Do NOT use for unfiltered browsing; use catalog.list. Do NOT use for CrossingKey digital/service offers; use offers.list. For one exact capabilityId use capability.get.
`catalog.list`read-only	FREE MARKETPLACE UNFILTERED DISCOVERY ONLY. Page through active public marketplace capabilities when no search filters are needed. Metadata is free; execution, entitlement, delivery, and purchased output remain gated. Do NOT use for filtered discovery; use capability.search. Do NOT use for CrossingKey digital/service offers; use offers.list. For one exact capabilityId use capability.get.
`commerce.quote`read-only	FREE MARKETPLACE PAYMENT QUOTE ONLY. After selecting an active marketplace capabilityId, return authoritative gross price, CrossingKey fee, provider share, and x402 v1/v2 payment requirements. A quote grants no entitlement and performs no execution. Do NOT use for first-party paid capabilities; use cost.estimate (first-party x402 capabilities have fixed catalog prices and no quote stage). Do NOT use for generic price lookup; use cost.estimate. Paid marketplace execution requires capability.purchase with authorization and verified payment.
`cost.estimate`read-only	FREE read-only cost estimate. This tool never creates checkout, reserves funds, or contacts a facilitator.
`creator.apply`destructive	FREE WRITE. Private creator intake for assets needing a capability model. No ownership transfer and AI training defaults false.
`credits.options`read-only	FREE read-only legacy credit compatibility status. New prepaid-credit sales are disabled in v4; historical paid credits remain redeemable through a separate compatibility path.
`execution.preflight`read-only	FREE read-only execution preflight. Returns READY_FOR_HUMAN_AUTHORIZATION only; it never authorizes, purchases, settles, executes, or creates records.
`hash.encode`	PAID $0.01 USDC on Base via x402. Computes a SHA-256 digest and UTF-8 byte count for supplied text. Calling this MCP tool returns a payment challenge and does not autonomously spend funds.
`json.repair`	PAID $0.01 USDC on Base via x402. Validates JSON and repairs a limited set of formatting errors. May return supplied content. Calling this MCP tool returns a payment challenge and does not autonomously spend funds.
`machine_commerce.readiness_audit`	PAID $2.00 USDC on Base via x402. Checks machine-commerce discovery and health surfaces. Calling this MCP tool does not spend funds; it returns the exact PAYMENT-REQUIRED challenge and canonical paid execution endpoint.
`marketplace.describe`read-only	FREE, read-only marketplace overview. Use this first for marketplace-specific capability commerce, fee policy, creator rights, payment rails, and active catalog counts; use provider.describe for the broader CrossingKey provider and legacy offer surface.
`mcp.launch_audit`	PAID $9.00 USDC on Base via x402. Performs bounded live MCP discovery, health, transport, schema, and receiver-only checks against a public endpoint. No payment is attempted by the audit.
`mcp.schema_audit`	PAID $1.00 USDC on Base via x402. Scores supplied MCP tool schemas for discoverability, descriptions, and bounded input contracts. Calling this MCP tool does not spend funds; it returns the exact PAYMENT-REQUIRED challenge and canonical paid execution endpoint.
`offers.list`read-only	FREE read-only public offer and capability discovery. This tool never starts payment or execution.
`openapi.quality_audit`	PAID $1.00 USDC on Base via x402. Evaluates structural quality and required fields in an OpenAPI document. Calling this MCP tool does not spend funds; it returns the exact PAYMENT-REQUIRED challenge and canonical paid execution endpoint.
`pii.scan`	PAID $0.01 USDC on Base via x402. Detects selected personal-data patterns and returns classifications and positions, not matched values. Heuristic, not comprehensive. Calling this MCP tool returns a payment challenge and does not autonomously spend funds.
`prompt.audit`	PAID $0.01 USDC on Base via x402. Scores selected prompt structure signals using deterministic heuristics. Calling this MCP tool returns a payment challenge and does not autonomously spend funds.
`provider.apply`destructive	FREE public application intake. Always pending, never creates credentials or active capabilities.
`provider.describe`read-only	FREE read-only provider and commerce policy discovery. Use this before selecting an offer or capability.
`provider.get`read-only	FREE. Public active provider metadata. Pending applications require owner or administrator authorization.
`requirements.check`read-only	FREE read-only requirements check. This tool never authorizes or starts payment or execution.
`result.preview`read-only	FREE read-only result-shape preview. This tool never executes a capability or creates an entitlement or receipt.
`secret.scan`	PAID $0.01 USDC on Base via x402. Detects selected credential patterns and returns classifications and positions, not matched values. Heuristic, not comprehensive. Calling this MCP tool returns a payment challenge and does not autonomously spend funds.
`x402.compatibility_audit`	PAID $1.00 USDC on Base via x402. Audits an x402 endpoint for v1/v2 compatibility defects. Calling this MCP tool does not spend funds; it returns the exact PAYMENT-REQUIRED challenge and canonical paid execution endpoint.
`x402.purchase_path_audit`	PAID $19.00 USDC on Base via x402. Performs a bounded no-payment purchase-challenge audit for a selected capability, validating status, requirements, destination, amount, and receiver-only controls.
`xkey.validate`	PAID $0.10 USDC on Base via x402. Validates and normalizes one bounded XKEY intake payload. Calling this MCP tool returns the exact PAYMENT-REQUIRED challenge and does not spend funds.
