"Payments" matching MCP servers:

Free JSON Schema validation, JSON to TypeScript, CSV to JSON, JSON repair and JSON to CSV for AI agents. Hosted MCP plus local STDIO. Connect once with a scoped key; enforce tool allowlists and quotas, inspect request IDs. Runnable repair → validate → CSV workflow. Bounded OpenAPI and webhook checks. No LLM calls or payments. Setup: invokeport.com/agents.

Behavioral verification intelligence for AI coding agents. Reads a TypeScript or JavaScript repo, clusters functions into 25 semantic workflows (Authentication, Payments, Webhooks, Caching, Queue, and more), and emits concrete adversarial probes per workflow. 17 MCP tools, local SQLite state, zero cloud.

An MCP server that provides a readiness gateway for ISO 20022 payments, offering readiness checks, automated remediation, clearing-profile linting, and bank-response simulation through a single orchestration interface.

Exposes a fictional small business as 46 MCP tools spanning CRM, inbox, calendar, invoicing and phone, letting agents read and modify customers, deals, messages and payments with validated, audited writes that stay inside the process.

Enables AI agents to obtain an independent review of their drafts, returning a pass/fail verdict with specific issues and suggested fixes, plus a signed receipt. Payments are made per check over x402, with no account or API key needed.

Enables AI agents to test Cashfree payment integrations end-to-end by creating orders, simulating payments, listening to webhooks, and verifying signatures via MCP tools.

Validates regex, cron, and SQL expressions by executing them in real runtimes, with payments via x402 USDC on Base.

Enables MCP clients to list and inspect evaluation tasks, score model answers, run the full benchmark, and retrieve provenance information.

Enables AI coding agents to safely integrate cross-border payments by providing structured payment knowledge, deterministic validation of idempotency, security, and state-machine rules, webhook testing, executable pytest generation, and diagnosis for Python/FastAPI Checkout projects.

An MCP server that mocks payments, third-party API responses, and test data to enable QA flows for donation, checkout, SIP, and subscription pages without depending on a live gateway.
