GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Discover and pay for services from the Nevermined Catalog using a spend-capped budget.
Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
Search Fragments — two tools for the queries an agent can't place, both built to decline rather than guess. resolve_fragment takes a half-remembered, cross-source query ("a musician who became famous for stopping performing") and returns a grounded answer, ranked web sources to confirm by eye, or an explicit no-resolution. verify_claim takes a specific factual assertion and returns supported, partially_supported, insufficient_evidence, or unsupported, with cited evidence and a stated_limits field that is always present. There is no confidence score — insufficient_evidence fires freely, and unsupported requires a source that explicitly contradicts, never mere absence of confirmation. Every verdict is decide-by-eye: "supported" means current web sources confirm it, not that the claim is true. Calibrated against 18 known claims before release. Free, no signup. Streamable HTTP (MCP 2025-11-25). Read-only.
Signed, traced record of what an npm package or file attempts when run, network included. No key.
Agentic Finance: 500+ agent tools, multi-chain USDC over x402 or MPP, or free via proof-of-work
360 pay-per-call APIs for AI agents over x402 and MPP, settled in USDC on Base ($0.001-$0.25 a call, no account or API key). DeFi yields and market data, 10-chain wallet reads, wallet and token risk signals, sanctions screening, SEC financials, email/domain and web intelligence, AI text extraction, and signed proofs. Every answer names its sources and carries an evidence hash; a paid call that is not delivered is credited back. Built and run by UnyKorn LLC.
Simulate cloud infrastructure and estimate cost before deploying or changing infrastructure.
Public chauffeur information, policies and anonymous price previews for Munich and MUC. On explicit customer request, prepare a binding unpaid offer using email OR E.164 phone, without an account. Customers review bound terms and explicitly confirm in Samuelz checkout. The same endpoint provides OAuth-protected booking status, payment review, history, and amendment/cancellation workflows. Booking data and actions require authorized customer access; changes and cancellations require the applicable object-bound consent. Tool discovery is public. Quotes do not guarantee availability, and MCP does not take payment.

Fastio gives your team and AI agents a workspace for each project, bringing source files, comments and new work together. Connect a compatible MCP client to find files, answer questions from project material, and save results where the team can review and use them. \ Sign in through Fastio and choose the workspaces the connection can reach. Read Only connections expose read tools; Read & Write connections also allow changes. \ • **Files and folders:** browse, read, upload, and organize files, with version history and trash. • **Search:** find files by keyword; search file content and meaning when Deep Indexing is enabled and files have been processed. • **Metadata:** read, set, and search metadata fields, including extracted fields where available. • **Shares:** create and manage shares for sending or collecting files. • **Comments and members:** read and add comments, and manage workspace membership within your permissions. • **Activity:** search workspace events to see what changed. \ Hosted by Fastio, with no server installation required. \ • **Claude and most MCP clients:** https://mcp.fast.io/mcp/tools • **ChatGPT:** https://mcp.fast.io/mcp/operations • **ChatGPT and Codex:** Fastio plugin • **Claude Code, Cursor and similar coding agents:** https://mcp.fast.io/mcp/code • **Setup and client-specific capabilities:** https://mcp.fast.io/docs \ Paid plans. Monthly plans include a trial of up to 30 days. A card is required, and billing begins when the trial ends or trial credits run out, whichever comes first. No free plan.
Real, bindable home & auto insurance quotes via MCP — actual carrier rates, not estimates. Texas today, expanding across the US. AI agents can check eligibility, run a live multi-carrier quote, compare options (carrier names hidden until bind), and hand the customer a secure link where a licensed agent finalizes coverage — never an automated purchase. No sign-up or API key required; optional free partner keys for integrators.
Scan a site or AI-built app for exposed databases, keys and MCP endpoints, then verify the fixes.
Paid web research, fact-check, page summary and page extraction tools for AI agents. Pay per call in USDC with x402 (Base or Solana). A failed call is not charged.
teas.co.uk is an independent UK shop with more than 600 teas, coffees and hot chocolates from 60 brands. This connector searches the live catalogue in plain words, such as a strong breakfast tea or something caffeine free for bedtime, with filters for type, caffeine, milk, time of day, strength, pack size, price per cup and organic, Fairtrade or vegan labels, and shows live prices and stock. Open any product for tasting notes, a brewing guide and recipe ideas, or compare up to four side by side. Build a basket and get a secure checkout link: payment always happens on teas.co.uk, never in the chat, and the connector cannot place an order. Customers who link their teas.co.uk account (OAuth) can see orders and courier tracking, buy again, manage repeat deliveries, check reward points and start a return. teas.co.uk delivers to the UK, the Channel Islands, the Isle of Man and many European countries; prices are in pounds including VAT.
ai-mail.sh gives your AI agent its own email address for $0.05, paid with x402 (USDC on Base), with no signup. Verification codes and links come back already extracted, and wait holds the request until mail arrives. Addresses are never reassigned: come back months later, pay again, same address. Receive-only, no tracking, and you delete it, it's gone. Works over HTTP or MCP.
Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
Free deterministic security scan of public git repos: OSV.dev vulnerable deps, secrets, config lint.
Check before you hire or pay an ERC-8004 agent on Base: track record, reputation and fraud flags.
Give your AI agent persistent, governed memory for every project. At task start it recalls the approved decisions, conventions, risks and architecture (semantic search, ranked by importance); at close it proposes what was learned as typed memories that you review and approve — governance, not a notes dump. Agents propose, humans govern: edits go back to pending and deletion is human-only by design. Connect Claude Code, Cursor, Claude Desktop or any MCP client in two minutes with just your API key — hosted (nothing to install) or locally via `uvx solucortex-mcp`. Built by SoluAI and dogfooded daily: SoluCortex is developed using its own living memory.
