"Connect to MySQL server, edit database structure, and run manual migrations" matching MCP servers:

Your AI agent can't touch Stripe, Gmail, Slack or more, without your tap. mild.run intercepts every sensitive action and sends you a notification to approve or block — before anything executes. Agent never holds credentials.

Enables AI agents to resolve social handles to wallet addresses, check reputation scores, and send tokens directly from any MCP-compatible client.

Enables managing Apple App Store commerce via natural language, with secure keychain storage and write confirmation for all revenue-impacting operations.

Discover audio and LLM services, compare seven voices, and check prices for free. Generate speech, transcribe audio and request LLM text with optional capped USDC payments on Base; voice-cloning requirements are also available.

Credit and payments for AI agent developers — over MCP. No crypto required

Read-only access to Stripe data including customers, charges, subscriptions, balance, and invoices.

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.

MCP server for the Gravv payments API that lets AI assistants onboard customers, run KYC, open accounts, move money, issue cards, and exchange currency, with built-in documentation search and safety confirmations for money-moving operations.

Enables AI agents to gate real-world side effects through a durable decision record, ensuring at-most-once initiation, deduplication, budget enforcement, and auditable outcomes across retries and failures.

Enables AI coding assistants to log billable hours into the Keeping time-tracking service via MCP tools, with dry-run protection for all write operations.

Budget, approval, and receipt layer that agents call when they buy on a human's behalf. MCP server with dry-run by default.

Exactly-once execution for irreversible agent actions: an agent claims the right to run an effect, and a retry after a lost response returns the sealed result instead of charging again. 12 tools over stdio, including a gateway mode where the agent holds a single-use ticket and never the provider key.

Enables AI assistants and agents to vet a stablecoin or x402 payment before it is sent, returning an approve, hold, or reject decision from instant rule checks and an optional locally-run risk model. Fails closed, so malformed input or an unreachable model yields a hold rather than an approval.

MCP server exposing a Lightning wallet to LLM agents over Nostr Wallet Connect (NIP-47): balance, invoices, LN address/LNURL payments, batch pay, and keysend. All spend tools are wrapped in a defense-in-depth safety stack — budget caps, allowlist, two-step confirmation, audit log.

Enables agents to run image A/B preference tests with human participants, retrieve live pricing and availability, create and purchase studies within configured USDC spending limits, and check vote results.

Lets Claude run a small online store's back office — searching customers, looking up and listing orders, generating sales reports and low-stock alerts, updating order status, issuing refunds, and creating invoices — with server-side guardrails like refund caps, idempotency keys, an order state machine, and audit logging on every write. Includes a deterministic eval harness that grades agent behaviour against the actual database state.

Enables Claude to interact with a Folio business bank account for managing accounts, transactions, receipts, bookkeeping, and payments as drafts.

Lets AI clients call paid x402ai endpoints — embeddings, summaries, and short answers — paying per call in USDC on Base via the x402 protocol, with per-payment and per-session spend caps plus a free inspector for decoding any x402 endpoint's payment challenge. Runs locally over stdio, needs no hosted account, and can operate in quote-only dry-run mode.

Enables AI agents to read and change jobs, job status, customers, quotes with line items, invoices, quote and invoice email, payments, and Scheduler bookings in an account by reusing the user's own signed-in Chrome session, with no official API keys needed. Ships read-only hints and confirmation prompts for tools that reach other people, and can be run over stdio or streamable HTTP.

Enables users to access transaction reports and exports, create payment links, and optionally match payments to a payer roster workbook through an MCP interface.

Invoice by Ouroboros Apps (https://ouroborosapps.com). Freelance invoice records: approved invoice line items, quantities, agreed rates, due dates, and late terms; invoice changes need explicit approval. Connect by pasting https://invoice-continuity2.vercel.app/mcp into Claude, Cursor, Grok, or ChatGPT developer mode (OAuth). Docs: https://ouroborosapps.com/docs/invoice

Stdio bridge for Frantic's live bounty-board MCP. Use npx -y frantic-mcp in stdio-only clients; remote clients connect at https://api.gofrantic.com/mcp. Browse funded work, claim bounties, submit artifacts and inspect the public receipt ledger. Posting and funding use Base USDC through x402; agents are paid after accepted delivery. Guide: https://gofrantic.com/AGENTS.md.

AI payment guardrails for Python & MCP: spend-capped agent identity (KYA), dry-run/budget/approval gates, prompt-injection defense, encrypted secret vault.

Connect Peil to Claude (or any MCP client): log hours, draft invoices from unbilled hours, and check where you stand — from a prompt.

Paybond Kit for Python is the PyPI package for tenant-bound Paybond integrations and delegated agent spend controls. It opens hosted Gateway sessions, verifies capability tokens, authorizes tool-call spend, signs intent and evidence payloads, uses Stripe Connect, Stripe ACH Direct Debit, or x402 / USDC-on-Base settlement rails, reads tenant-scoped Signal, fraud, ledger, protocol, and A2A data, and

Connects AI agents to Bitcoin payment rails with owner-defined spending policies and limits.

Enables AI assistants to search real products, purchase with user approval, track deliveries, and run a seller business end to end via the Firestarter commerce platform.

Enables MCP clients such as Claude Code, Claude Desktop, and Cursor to communicate over stdio with the IMD swarm API to check evaluator verdicts, import public GitHub repositories, get quotes, and pay quoted orders through the x402/Permit2 flow with spend caps, dry-run safety, and configurable wallet signing.

Enables agents to analyze X creators' niches, audiences and engagement, estimate sponsored-post prices with a transparent formula, rank creators against a brand brief, and run deals from offer through post verification to a recorded payout ledger. Every write is previewed and confirmed by a human, and the server never posts to X or moves money.

Lets AI agents work inside a creator account to create short links and paywall links, fill access code pools in bulk, and upload galleries, videos, and multi-episode series straight from the local computer to the user's own Bunny storage. Uploads run in the background with progress tracking, and payment holds can be confirmed or rejected on request.
