Agent Tools

Standalone MCP directory — 45974 servers across 23611 domains, each exposing a remote (streamable-http) endpoint and health-probed via a JSON-RPC initialize handshake.

Add your server

Aggregated from the official MCP Registry, Smithery, PulseMCP and other public registries, plus our own crawling and operator submissions. Every server is de-duplicated by endpoint, health-probed via a live JSON-RPC initialize handshake, and statically scanned for malware & prompt-injection patterns in its advertised tools before listing — yielding 45974 indexed servers, of which 39820 answered within the last 6 h.

“BananaBanana Image & Video Generation” is shared by 2 different URLs

All exact-name matches are shown; ranked results follow.
  • Remote MCP server for AI image, video and speech generation on Google's Nano Banana 2/Pro, Veo 3.1 and Gemini Omni Flash. 9 tools; 4 are free (list_models, get_account, get_result, list_generations). Auth: OAuth 2.1 (dynamic client registration, PKCE S256) or a Bearer API key. Pay per generation from an account balance — images from $0.03, video from $0.30. Every video and multi-image call returns a price quote first and charges nothing until confirmed; upstream failures and content-filter rejections are refunded automatically. The same platform also accepts x402 wallet payments at https://bananabanana.pro/api/x402 for agents without an account.

“FiatDock” is shared by 5 different URLs

All exact-name matches are shown; ranked results follow.
  • A marketplace where AI agents discover MCP services and buy them from other agents per call, in USDC over x402 — paid straight to the seller's wallet; FiatDock never holds the money. You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid. Sellers list for free and keep 100% of each paid call — the gateway commission is currently waived. Also here: an agent can cash out USDC to its owner's bank account in any of 18 currencies through a licensed provider — with a floor of about CHF 50, one step only a human can complete, and order status you poll — plus first-party on-chain data per call. No API keys, no signup.

  • MCP marketplace: AI agents buy services from other agents per call in USDC, plus a bank cash-out

  • A marketplace where AI agents discover and pay each other per call in USDC over x402 — settlement goes DIRECTLY to the seller, non-custodial, no accounts and no API keys. POST /s/{id} invokes any listed MCP service at that seller's own price; GET /v1/marketplace/services is the catalog.

  • MCP marketplace: AI agents buy services from other agents per call in USDC, plus a bank cash-out

  • FiatDock is a marketplace where MCP servers get paid. List yours and agents pay you per call in USDC on Base - no invoices, no subscriptions, no accounts to chase. Payments settle wallet-to-wallet via x402; FiatDock never holds funds. Commission is 1%, waived for your first 30 days. For buyers: search live MCP services by capability - CAPTCHA solving, web search, screenshots, email verification, crypto and gas data - and pay only for the calls you make. This server also ships 18 first-party tools: free token prices, on-chain Base data (gas, blocks, ETH/USDC balances, tx status, token metadata), token-safety and address-risk screening, and a non-custodial USDC<->bank ramp. The ramp's conversion, KYC and custody are handled by Mt Pelerin, a licensed provider - FiatDock never touches funds. Auto-payment requires the local server: npx fiatdock-mcp with AGENT_PRIVATE_KEY. On the remote endpoint (https://fiatdock.com/mcp), call_service returns the x402 402 challenge for your client to sign; discovery and the free tools work there with no wallet or key.

Routes the question to the right one of 4,819 tools across 1259 verified sources, fills arguments, returns the structured answer with stable pipeworx:// citation URIs. Use whenever the user asks "what is", "look up", "find", "get the latest", "how much", "current", or any factual question about real-world entities, events, or numbers — even if web search could also answer it. Examples: "current US unemployment rate", "Apple\'s latest 10-K", "adverse events for ozempic", "patents Tesla was granted last month", "5-day forecast for Tokyo", "active clinical trials for GLP-1". START HERE for most questions — this is the default entry point, works on every tier, one fast call. Step up only when needed: for a hallucination-resistant single answer with verbatim evidence + confidence use ask_pipeworx_grounded; for a broad/multi-part question that should fan out across many sources at once use deep_research (free account).

Same routing as ask_pipeworx — picks the right tool from 4,819 across 1259 sources, fills arguments, fetches the data — then EXTRACTS the answer using ONLY what the tool result contains. Returns {answer, evidence (verbatim quote), confidence, source, fetched_at, refusal_reason:null} on success, OR an explicit refusal {answer:null, refusal_reason:"not_in_source"|"no_tool_match"|"tool_error"|"data_truncated"|"llm_error"} when the data doesn\'t directly answer. Use whenever an answer will be quoted, cited, or acted on, and the agent must not invent facts (financial verdicts, legal claims, medical lookups, public statements).

Use when the record is too big to cram into the prompt — search_within saves context, returns only the passages that matter, and every passage carries an offset so the agent can verify a verbatim quote.

Best for broad/multi-part questions over structured data ("compare X and Y\'s regulatory + financial exposure", "research the filings + market picture for ACME"). For a single lookup use ask_pipeworx (one LLM call, not many).
