YieldAgentX402

Yax Get Capabilities

Returns every tool available on this server, what each one does, and when to use it. Call this first when connecting to understand the platform.

Yax Run Secure Workflow

Requests a governed agent action. Returns a run ID and policy decision; a terminal receipt is sealed, while HMAC signing, TEE binding, settlement, and provider-verified anchors are reported only when the corresponding evidence is produced.

Yax Delegate To Agent

Delegates work to another agent by spawning a child orchestration run linked to your parent run. Optional hireFeeUsd triggers policy-gated x402 or ledger hire payment. Child runs inherit min(parent, child) spend caps.

Yax Process X402 Payment

Pre-authorizes a gas/sponsorship budget for a governed hub-scoped agent, subject to hub attachment, Agent Pack grant, and policy checks. This does NOT sign, broadcast, or settle an on-chain transaction — it only reserves budget against your daily/per-transaction sponsorship cap. No transaction hash is produced.

Yax Check Policy

Checks if an action would be approved by your policy without running it. Returns approved/denied, remaining spend cap, and whether human approval is required.

Yax Get Receipt

Fetches the stored receipt for an authorized past run. Returns policy result and available hashes, signing state, conditional TEE evidence, anchor references, and stored provider-readback verification evidence without upgrading missing evidence.

Yax Verify Receipt

Projects stored receipt verification evidence. verified is true only when the stored payload HMAC was cryptographically checked and a provider GET readback matched the uploaded artifact; this call does not perform a fresh provider lookup.

Yax List Runs

Lists recent agent runs with status and policy result. Filter by outcome (approved/denied/escalated) to audit activity or find run IDs for receipt lookup.

Yax Submit Approval

Approve or deny a pending policy approval token for the authenticated agent.

Yax Control Workflow

Stop (cancel) or resume (approve human gate) an orchestration workflow run for this agent.

Yax Get Wallet Status

Returns the agent's wallet balance, spend cap, remaining cap for this period, and wallet address. Use before a payment to confirm funds are available.

Yax Score Leads

Scores inbound leads by conversion likelihood and syncs enriched records to your CRM. Returns each lead with a score (0–100), tier (hot/warm/cold), and enrichment data.

Yax Enrich Lead Data

Parses a raw lead email, form submission, or webhook payload into a structured contact record, enriches it, and logs it to your CRM. Returns name, email, company, phone, and ICP score.

Yax Build Email Sequence

Builds a personalized cold email sequence for a list of prospects. Researches each prospect and writes tailored copy. Returns subject lines, body, and send schedule per prospect.

Yax Monitor Churn Risk

Flags customers at risk of churning based on usage and payment patterns, and drafts a re-engagement email per account. Returns a prioritized risk list with churn score and outreach copy.

Yax Get Attestation

Reports whether TEE verification inputs are configured for this MCP Worker. It does not probe an enclave or verify a current attestation; use claim-specific verification and receipt evidence before relying on a TEE claim.

Yax Audit Compliance

Audits recent agent activity against policy rules and flags violations. Returns compliant vs flagged counts and report evidence; any storage CID is an anchor reference until provider readback/content match is separately verified.

Yax Collect Ar Invoices

Analyzes open invoices by age (30/60/90+ days) and sends escalating follow-up emails to overdue clients. Returns invoice count, total overdue amount, and emails sent per bucket.

Yax Forecast Cash Flow

Generates a week-by-week cash flow forecast across base, optimistic, and pessimistic scenarios. Returns projections and any report storage reference without representing CID presence alone as verified anchoring.
