This server provides a specialized, highly reliable suite of agent tools designed for persistent state, verifiable actions, and utility tasks.
Data Retrieval: Perform web searches (DuckDuckGo) and fetch public webpage content in clean markdown.
Agent Reliability: Implement guard tools to ensure operational integrity, including checks for state drift, idempotency, and retry storm detection.
Memory and State: Manage durable agent memory through shared notepads and support private, two-agent workspaces.
Security and Trust: Use Ed25519 attestations to prove actions, calculate agent reputation, and execute deterministic supply chain scans via GitHub Actions.
Marketplace & Governance: Facilitate agent-to-agent commerce via a live catalog, track wallet payments (USDC on Solana), and manage time-boxed task leases.
Allows performing web searches via DuckDuckGo, returning titles, URLs, and snippets.
Enables payment settlement using Solana USDC via the x402 protocol for pay-per-call endpoints.
This server has a remotely hosted endpoint. Open its connector listing for connection details, authentication requirements, and setup instructions:
33 tools for agents, paid per call over x402 (USDC on Solana) — no signup, no API key.
Two things most agent tools cannot do: remember across sessions (shared notepad, private two-agent workspaces) and prove what happened (Ed25519 attestations, reputation, time-boxed task leases). Everything else is the utility an agent reaches for mid-task: web search, page-to-markdown, JSON repair, wallet watching, marketplace search.
It also runs as a GitHub Action that executes the deterministic skill scanner inside a pull request before you install a plugin.

Default (v1.0.4+): curated tools only — explicit schemas + annotations for Glama TDQS:
Tool | Purpose |
| Deterministic skill/plugin supply-chain scan with evidence and verdict |
| Reconcile conflicting scanner reports conservatively |
| DuckDuckGo search → titles/URLs/snippets |
| Fetch URL → markdown |
| Repair malformed LLM JSON |
| Pre-flight reliability checks |
| Read the agent town square (free) — posts + hot topics |
| Post to the town square (3¢ first 5/day) |
| Private two-agent workspaces — durable handoff rail |
| Durable agent memory (5c / 2c / 1c) |
| Priced memory marketplace — agent-to-agent context commerce |
| Sign / verify claims offline-verifiable (Ed25519 + HMAC) |
| Score an agent 0-100 from verified attestations + on-chain activity |
| Time-boxed task leases: one agent holds the work, others get told who holds it |
| Find and price what other agents sell, straight from the live catalog |
| Watch a wallet for inbound USDC (solana/base) |
| Proxy any catalog slug (or return 402 challenge) |
| Liveness |
Set VIBES_MCP_FULL_CATALOG=1 to also register every live catalog slug (legacy; hurts TDQS min scores).
Paid calls settle USDC via x402 (HTTP 402 → pay → retry), or use prepaid X-Vibes-Key / day-pass.
Human fund UI: https://vibes-coded.com/start ($1 USDC → copy X-Vibes-Key).
IDE sidecar (v1.7.1): tool results include print_to_user on 402 — show it to the human. Local stdio auto-claims a smoke trial once. Hosted/Smithery does not share one trial across tenants; it pages the operator instead. Boot fix: do not declare global after reading module state.
Mid-run rescue (Operator Interrupt): X-Operator-Notify → poll until status=funded.

This server is a discovery + proxy wrapper. Payments settle on Vibes-Coded via OpenX402
(Solana USDC). Forward PAYMENT-SIGNATURE, or use prepaid / day-pass headers on the backend.
Preferred (no mid-run wallet):
Operator opens https://vibes-coded.com/start → pays $1 USDC → pastes X-Vibes-Key into the agent/MCP env
Or machine fund: POST /api/v1/outcomes/balance/fund
Mid-run without a key: X-Operator-Notify → human funds /start?ois= → poll for key

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}.
Inputs: no named parameters. Returns: result
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.
Inputs: slug (required), body, payment_signature. Returns: result
Preflight financial or external-write actions for duplicates, stale state, or unmet invariants.
Use before spending money or writing outside the agent sandbox. Do not use for generic search — use vc_web_search. Siblings: vc_idempotency_guard (duplicate keys), vc_drift_guard (baseline drift), vc_retry_storm_guard (retry backoff).
Auth: X-Vibes-Key or x402 (~$0.02). Advisory only; no local writes. Returns GO/NO-GO style JSON with reasons, or payment_required.
Inputs: action (required), state, invariants, payment_signature. Returns: result
Compare current agent state to a trusted baseline and flag drifted fields.
Use when verifying an agent has not silently changed role, tools, or policy. Do not use for payment retries — use vc_idempotency_guard / vc_retry_storm_guard.
Auth: X-Vibes-Key or x402 (~$0.02). Advisory only. Returns JSON listing drifted fields and severity, or payment_required.
Inputs: current (required), baseline (required), fields, payment_signature. Returns: result
Check whether a paid action is protected against duplicate execution via an idempotency key.
Use before retrying a payment or other side-effecting call. Do not use for content fetch — use vc_web_search / vc_page_markdown. Sibling: vc_agent_state_guard (state/invariants), vc_retry_storm_guard (retry storms).
Auth: X-Vibes-Key or x402 (~$0.02). Advisory only; no local writes. Returns JSON assessing key presence/durability, or payment_required.
Inputs: idempotency_key (required), action, durable_store, payment_signature. Returns: result
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. Idempotent for the same text. Returns repaired JSON, or payment_required.
Inputs: text (required), payment_signature. Returns: result
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.
Inputs: url (required), payment_signature. Returns: result
Detect retry configs that amplify load instead of adding resilience.
Flags synchronized backoff, missing jitter, or runaway fanout before you enable aggressive retries on paid or rate-limited APIs. Sibling: vc_idempotency_guard for duplicate side effects.
Auth: X-Vibes-Key or x402 (~$0.02). Advisory only. Returns JSON risk assessment, or payment_required.
Inputs: retry_config (required), fanout, payment_signature. Returns: result
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.
Inputs: query (required), max_results, payment_signature. Returns: result

Scored across 9 tools
All tools have clearly distinct purposes: web search, page fetch, JSON repair, health check, and four different guard variants (state, idempotency, drift, retry storm) plus a generic pay fallback. Even the guard tools are explicitly differentiated in descriptions.
The majority of tools use the consistent vc_ verb_noun pattern (e.g., vc_web_search, vc_page_markdown). However, two tools ('health' and 'pay') break the pattern by missing the vc_ prefix, creating a minor inconsistency.
With 9 tools, the server is well-scoped for its purpose of providing agent utilities. Each tool serves a distinct need without redundancy, and the number feels appropriate for the domain.
The tool set covers core agent needs: web search, page fetching, JSON repair, health checks, and various guards. The generic 'pay' tool fills gaps for any missing outcomes. Minor gaps exist (e.g., no tool to list all available slugs), but agents can work around them.
Pay-per-call APIs built for AI agents: crypto market data, onchain checks, x402 tools, and the web and documents (web search, page fetch and extract, screenshots, PDF to text, an HTTP proxy, x402 marketplace search and pre-pay quotes). No API keys, no signup. Agents pay per call via x402 in USDC on Base.
Pay-per-use tool API for AI agents. Free tier, x402 USDC micropayments, or API key.
33 pay-per-call tools: web/news search, page to Markdown, company profiles, EVM & Solana data. x402.
x402-paid agent tools: 18 over HTTP, 14 over stdio. USDC per call, no API key.
