"Local" matching MCP servers:

Enables AI agents to call paid APIs and settle HTTP 402 payment challenges with USDC on Base, without private keys ever being involved.

Enables AI agents to discover and pay for x402-gated HTTP APIs, handling 402 Payment Required flows with local signing. Supports EVM and Solana with non-custodial wallet management.

Enables AI agents to call LLM APIs via x402 micropayments in USDC on Base network, manage a local wallet, and query consumption records.

A template for building MCP servers with a built-in paywall gate that offers free local execution and premium server-side execution via Stripe and x402 payment lanes.

Enables running a local MCP server for Poland's KSeF (Krajowy System e-Faktur) e-invoicing system, so invoice data stays on the user's own machine rather than passing through an intermediary service. It currently exposes only a diagnostic server_info tool, with invoice search and retrieval tools still to come.

Enables issuing credit notes and credit memos against an invoice or standalone as revisable drafts that can be finalized into frozen numbered documents, then rendered as Markdown or printable HTML with totals broken down by currency, reason and month. All amounts are handled as integer minor units and all data stays local, so nothing is sent anywhere.

Payment firewall for AI agents: a signed, independently verifiable verdict on every money-moving action. Blocks wrong/lookalike payee, over-cap, and duplicate-invoice (BEC) fraud before money moves — anyone can verify a verdict against the public JWKS. Free, local-first, non-custodial.

Enables AI agents to stamp, cancel, and query Mexican CFDI 4.0 invoices through MCP tools, with support for local stdio and hosted HTTP transport.

A local MCP server that integrates ProofJSON to assess invoices before payment, providing allow/review/block decisions with confidence scores and verification capabilities.

Unofficial MCP server to operate MakeLeaps clients, quotes, and invoices from LLMs via the MakeLeaps API, with local execution and no telemetry.

Enables querying and downloading Equatorial Energia invoices via MCP tools, supporting listing consumer units, listing invoices, and downloading second-copy PDFs with local data extraction.

Enables AI assistants to parse, validate, send, and inspect X12 EDI documents via the SignalEDI Core API, with optional QuickBooks integration and a demo mode for keyless local testing.

Local, privacy-first access to bank and credit-card transactions for Copilot, backed by SimpleFIN.

A local MCP server providing payment validation tools and resources, including card number Luhn checks, card network detection, and IBAN validation, with no network calls required.

A local MCP server for Stripe payment operations with 52 tools across 8 domains, featuring built-in PII redaction and strict input validation for safe AI-assisted development workflows.

Enables AI assistants like Claude Code to query your bank balances and transactions through the Plaid CLI. It securely wraps Plaid CLI commands as MCP tools, keeping your credentials local.

Enables Claude to read UK bank account data—balances, transactions, cards, standing orders, direct debits, and identity—through TrueLayer's Data API, with local caching and optional live refreshes. It is read-only by design, requiring consent and never moving money.

Single-tenant MCP server for Polish KSeF e-invoice workflows, supporting local stdio testing, draft management, and invoice submission with safety gates.

Enables local MCP clients to query the dxpert.ai API using an API key. Users can ask advisory questions, run agents and diagnostics, convert CSV exports to bundles, and manage purchases.

Enables stdio-only MCP hosts like Claude Desktop and Cursor to securely connect to Payman's remote Genie MCP server, exposing the ask_genie tool for payments and finance tasks via a local bridge.
