Vibes-Coded Agent Security and Commerce Tools

Run a public web search and return titles, URLs, and snippets as JSON. Use when you need current public web results for a query. Do not use for private/intranet pages — call vc_page_markdown with a known URL instead. Sibling: vc_page_markdown (one URL), pay (generic slug caller). Auth: free-trial or prepaid X-Vibes-Key preferred; else USDC via x402 (~$0.02). Side effects: outbound HTTP to a search provider; no local writes. Returns JSON results, or a payment_required challenge if unpaid.

Fetch a public webpage and return clean markdown plus extracted text. Use when you already have a URL and need readable page content for an LLM. Do not use for search discovery — call vc_web_search first. Not for authenticated or paywalled pages. Auth: free-trial or X-Vibes-Key preferred; else x402 (~$0.02). Side effects: outbound HTTP GET to the URL; no local writes. Returns JSON with markdown/text fields, or payment_required.

Repair malformed JSON from LLM output and return valid parsed JSON. Use when a model returned broken JSON (trailing commas, missing quotes, etc.). Do not use for web fetching or search — use vc_web_search / vc_page_markdown. Auth: free-trial or X-Vibes-Key preferred; else x402 (~$0.02). Side effects: none local; compute-only remote call.

Verify an agent's completion claim against real external world state. Runs independent read-back checks (HTTP status, page text, JSON fields) and returns a digest receipt with verified=true/false plus a confidence score, so a user does not have to trust the agent's self-reported summary. Use after an agent says it posted, deployed, paid, emailed or changed a record. ~$0.25/call.

Mint a durable single-use capability lease, or attenuate a parent lease. Use before an irreversible action you may need to retry: pass a stable use_nonce to vc_lease_consume so a retry after a timeout blocks instead of writing twice. Authority is conserved — a child's uses are reserved out of the parent, so a 1-use grant cannot father N free children. ~$0.05/call.

Spend exactly one use of a lease, atomically. Blocks replay, expiry, revocation and overuse. Returns decision allow/block with a named reason plus an Ed25519 decision receipt.

Preflight financial or external-write actions for duplicates, stale state, or unmet invariants. Use before spending money or writing outside the agent sandbox.

Watch a wallet for new inbound USDC (payment-watch, 2c) — the 'did the money land?' check. Poll with the last signature as `since` to get only what's new.

Reconcile conflicting agent-skill security scanner reports. Use after running two or more independent scanners. Returns agreement, conflicts, conservative verdict, normalized scores, combined rule IDs, and an evidence fingerprint. Direct deterministic delivery: no second Vibes-Coded payment challenge is generated.

Scan an agent skill or plugin for supply-chain and credential-exfiltration risks. Use before installing untrusted SKILL.md files, MCP plugins, npm packages, or setup scripts. Direct deterministic delivery: no second Vibes-Coded payment challenge is generated. Returns a risk score, allow/review/block verdict, exact findings, and evidence lines.

Call any Vibes-Coded outcome by slug, optionally attaching an x402 payment signature. Use for catalog outcomes without a dedicated vc_* tool, or to retry after payment_required. Prefer dedicated tools (vc_web_search, vc_page_markdown, …) when they exist — clearer schemas. Do not use instead of health(). Prefer prepaid X-Vibes-Key / X-Day-Pass over per-call wallet signing (human fund: https://vibes-coded.com/start). Args: slug: Outcome id, e.g. "web-search" or "agent-state-guard". payment_signature: Optional x402 PAYMENT-SIGNATURE header value. body: JSON object of endpoint fields (query, url, text, …). Returns JSON result, or payment_required with pay_to/amount and fund tips. Side effects: may settle USDC via x402 when paying; otherwise HTTP only.

Return MCP server liveness: version, origin, tool count, and catalog size. Use for hosted inspector probes (Glama / Smithery) or before diagnosing tool failures. Do not use for business outcomes — call vc_* tools or pay(slug=...) instead. No auth required. No side effects. Returns JSON {ok, service, version, origin, tools, catalog_resources}.
