Enables AI agents to call Safaricom's M-Pesa Daraja API directly, sending STK push prompts, checking balances, looking up or reversing transactions, and receiving results as SUCCESS, FAILED, or UNKNOWN. Requests are sent once per idempotency key with sandbox-by-default operation, so agents can operate and test payments without risking double charges or real money.

Enables AI assistants to build PayRetailers cross-border payment integrations accurately by providing official documentation, endpoint specs, country-specific payload validation, webhook guidance, and integration prompts as MCP resources, tools, and prompts.

Let AI agents find and hire human help: search services, workers and jobs on GoHireHumans. Hiring and payouts need the account owner's authorization.

Enables AI agents to analyze payment gateway error messages and receive structured triage results, including likely causes, recommended checks, and retry safety guidance.

Performs static security analysis of Solana programs and generates x402 payment invoices for automated agent-to-agent audit workflows.

Enables conversational AI assistants to help users discover movies, find showtimes, book seats, and process payments for AMC Theatres through a simple API interface.

Open-source sample MCP server built to be audited: ships a paid-tool x402 demo, a deliberately scannable surface, and documented security posture. From Payload, makers of the MCP Launch Readiness Audit (48-rule scanner with a fix for every finding, hardening templates, stress-test harness, readiness verifier, CI workflow, branded audit report) and the MCP Monetization Kit.

Enables AI agents to access DDG's payable services including checkout/payment conformance, MCP/tool security audits, agent-discovery repair, and buyer-agent smoke probes, with structured payment challenges.

MCP services for agent security preflight, source scanning, injection screening, proof-of-work policy rehearsal, carbon accounting, climate disclosure and regulatory monitoring. Use each hosted endpoint in the README. Inspect a free quote before buyer-authorized x402/USDC payment. Includes free trust and settlement tools. Maxwell rehearsal does not activate runtime protection.

Enables AI assistants to pay for online purchases and subscriptions using one-time prepaid USD Visa cards drawn from the user's own wallet. Every charge requires explicit user approval, and each card is loaded with only the needed amount and freezes after a single payment.

Connects MCP clients to a telephony account so users can manage phone numbers, SIP accounts, routing, SMS, calls, and billing in plain language. It exposes search, schema lookup, and execute tools to run permitted API operations, with confirmation required for paid or destructive actions.

Enables users to plan, prepare, pause, and track connected-TV, digital street-screen, and mobile ad campaigns in plain language through any MCP client, from drafting budgets and audiences to adding creatives and retrieving performance.

Enables opening a Vivid Business account directly from an AI chat by sharing company details or documents, with automatic extraction and pre-filled setup.

Integrates PayU payment services with AI tools through the Model Context Protocol, enabling payment link creation, transaction retrieval, and settlement analysis.

Enables autonomous financial agents and payment systems to analyze transaction streams in real time, detect velocity-based fraud patterns such as card testing, volume spikes, and account takeovers, and produce balanced ledger records with audit telemetry.

An MCP server that enables AI agents to search, pay for, and call paid APIs using the x402 protocol, with automatic USDC settlement.

Enables autonomous financial agents to optimize payment recovery by analyzing decline-code retry windows and mitigating involuntary churn, while enforcing balanced double-entry ledger records, HMAC-SHA256 signature verification, and sliding-window fraud detection through an MCP-compatible interface.

Enables responders to discover, read, and answer data requests via the Reqport API, providing tools for health checks, request listing/reading, payload decryption, and responding to business-relationship or generic requests.
