Synth MCP Server

If you want an AI assistant working directly with Synth MCP, the synth mcp mcp server is the bridge. MCP server for Synth Finance API integration.

What Synth MCP does

A remote MCP (Model Context Protocol) server that provides AI assistants with access to the Synth Finance API. This server enables Claude Desktop and other MCP-compatible clients to access financial data, currency information, stock prices, insider trading data, and more through natural language queries.

Key capabilities

• 🏦 Transaction Enrichment — Decode cryptic bank transactions into clear merchant information with logos, locations, and categories
• 💱 Currency Exchange Rates — Access real-time and historical exchange rates for all major currencies
• 📈 Stock Market Data — Search tickers and retrieve historical OHLC price data
• 👔 Insider Trading Data — Access comprehensive SEC Form 4 filings and executive trading activity
• 👤 User Account Info — Check API usage, credits remaining, and account details

Installing the synth mcp mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Configuration

Before the server will start you need to supply one environment variable: YOUR_SYNTH_API_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Synth MCP sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

• This is a hosted server — you point your client at an endpoint rather than running a local process, so there is nothing to keep updated on your machine.
• It will not start until its required credentials are present, so set those before wondering why the tools never appear.
• Maintained by maybe-finance, written in Go.
• MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the synth mcp mcp server actually does with your data.
• Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
