"Understanding Prompts or Prompt Engineering" matching MCP servers:

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.

MCP server that validates and writes DATEV-Format (EXTF) files: Buchungsstapel (booking batches) and Debitoren/Kreditoren (customer and supplier master data). Ask your AI assistant why DATEV rejected an import, or have it turn a list of bookings into a file DATEV accepts.

Local, payload-free AI cost visibility for agents. Track spend by model, route, customer, or tagged work without storing prompt or response bodies.

Local MCP for Australian accountants: ATO benchmarks, Payday Super timing, limited Division 7A reviews, 7 bounded tax worksheets and cited legislation search, plus synthetic CTR/BAS test data. Experimental reviews need professional judgement. No advice or lodgements.

A read-only MCP server so AI agents can query the corpus or the live site.

Startup engineering acceleration signals for VC investors. Tracks commit velocity, contributor growth, and repo expansion across 20 sectors via public GitHub data. No API key required.

IBAN validation across 89 countries, BIC/SWIFT and Swiss clearing lookup, batch validation, payment-reference, postal-address and Swiss QR-bill checks for AI agents. Connect via MCP or the REST API. Includes free quotas, paid credits and a Pro subscription. SEPA and country-risk indicators support payment-data checks; they do not confirm account ownership or replace beneficiary AML/KYC screening.

Integrates the Metis FCA Handbook AI Harness into Claude Desktop to analyze FCA Handbook applicability for financial products, services, or firms, returning structured compliance reasoning with verbatim citations.

Keyless CEX/DEX order signing for AI trading agents (Binance, OKX, Bybit, KuCoin, Hyperliquid, Asterdex). Exchange keys stay inside an AWS Nitro Enclave — the agent gets policy-bounded signatures, never credentials. Built to survive prompt injection and supply-chain key leaks.

Enables currency conversion and exchange rate lookups using real ECB reference rates, free and without an API key. Supports natural language queries like 'convert 100 USD to EUR' or 'what's the exchange rate between GBP and JPY?'.

Compares AI coding tool spend before and after a migration -- Cursor, Claude Code, GitHub Copilot, OpenCode, Codex CLI -- via an MCP server, real numbers from each vendor's own API or local logs.

Free MCP server for real-time cryptocurrency data. Get token prices, market overview, top movers, historical charts, and detailed token info directly in Claude Code, Cursor, or any MCP-compatible AI tool. Powered by CoinGecko with 70+ token mappings and built-in caching.

Open-source, accountant-verified tax computation skills for AI agents. 261+ skills across 172+ jurisdictions covering income tax, VAT/GST, payroll, corporate tax, crypto, and cross-border planning. Every skill is verified section-by-section by licensed CPAs and chartered accountants. 3 tools (list_skills, get_skill, get_skill_sections) and 1 prompt (skill-review).

RiskModels decomposes any US stock or portfolio into market, sector, subsector, and residual risk components with executable ETF hedge ratios — enabling portfolio managers to understand risk exposure and construct precise hedges programmatically.

Provides complete FreshBooks integration with 87 tools covering accounting, invoicing, time tracking, expense management, client/project management, and financial reporting through OAuth2 authentication.

Enables AI assistants to query Polish new-build housing data: developers' asking prices with price history, real transaction prices from the RCN register, and GUS/NBP market statistics, plus searchable locations, offers, investments and developers. Exposes thirteen read-only tools over the public deweloperuch.pl data, usable from any MCP client or the bundled CLI.

Automates GSTR-1 filing through Sandbox.co APIs, enabling seamless integration with Claude Desktop or API for GST return submission.

Enables read-only, bounded quantitative-research workflows with schema compatibility checking and server capability discovery, without exposing market data or live trading.

Enables Claude clients to score borrower default risk, explain predictions with SHAP, compare applicants, and inspect model metadata through natural conversation. Serves a trained XGBoost model locally over stdio or remotely over HTTP with API-key authentication, keeping confidence transparent by reporting which inputs fell back to training-set defaults.

MCP server that scores the behavioral risk of a wallet on Base before sending it money. Provides a risk score, verdict, and explainable flags based on USDC payment history.
