Before you install.

Run npx -y @codespar/mcp-open-finance@0.2.2 and add the config block above to your MCP client: Claude Code, Cursor, Claude Desktop, VS Code, or any MCP-compatible client. No build step, no SDK required.

What can my agent do with Open Finance?

Open Finance exposes 18 tools for banking. Your agent calls them directly; the full list is above.

How does Open Finance authenticate, and how are credentials stored?

Open Finance uses OAuth2. Self-hosted, you hold the credentials: the server reads them from its environment variables.

How does Open Finance handle upstream API changes?

Every server is versioned independently on npm. The command on this page pins 0.2.2, the version whose tools are listed here; your agent keeps running it until you change the version.

Is Open Finance open source? How do I report a bug?

Yes. Open Finance is MIT-licensed and published on npm as @codespar/mcp-open-finance, source on GitHub (link in the Details panel). Report issues on the package repository; security issues go to security@codespar.dev, and we respond within 24 hours.
