One currency server,
every AI client.
Point Claude, ChatGPT, Cursor, VS Code, Gemini CLI or any Streamable HTTP client at the same URL. CurrencyCore handles OAuth, tool discovery and metering, so the agent can convert, look up history, apply PPP and run analytics without custom wrappers.
14 tools · OAuth 2.1 · Same quota as the REST API

Which AI clients work with CurrencyCore?
CurrencyCore works with Claude, ChatGPT, Cursor, VS Code, Gemini CLI, Windsurf, and any client that supports remote Streamable HTTP MCP with OAuth. Every client uses the same server URL, https://mcp.currency-core.com/mcp, and the same 14 currency tools. The server publishes OAuth protected-resource metadata and a server card for automatic discovery. MCP access is included on every plan, and each successful tool call counts as one API request.

Connect in the client you already use
Each guide covers the exact menu path, the OAuth step and the first tool call.
Claude
Settings → Connectors → Add custom connector → paste the server URL. Sign in and pick an organization.
Works on Claude Pro, Max, Team and Enterprise. The connector directory route is the one-click option when available.
ChatGPT
Settings → Connectors → Advanced → Developer mode → Add custom connector. Paste the server URL and complete OAuth.
Developer mode is available on paid ChatGPT plans on the web. A directory listing removes the developer-mode step.
Cursor
Settings → MCP → Add new MCP server, or add the URL to .cursor/mcp.json.
Cursor opens the OAuth flow on first tool call and stores the grant per workspace.
VS Code
Command Palette → MCP: Add Server → HTTP → paste the server URL.
Requires a VS Code build with MCP support in Copilot Chat.
Gemini CLI
Add the server to your Gemini CLI MCP settings and restart the session.
Uses the same OAuth discovery contract as the other clients.
Any MCP client
Point a Streamable HTTP client at https://mcp.currency-core.com/mcp and follow the 401 challenge.
OAuth 2.1 with PKCE, protected-resource metadata, and organization-scoped tokens.
Built for discovery
Agent directories read the same manifest and discovery documents that the server publishes at runtime.
CurrencyCore is published in the official MCP Registry as io.github.CurrencyCore/currency-core-mcp (version 1.0.0). The GitHub MCP Registry syncs new versions from that listing once a server is onboarded, and the same manifest powers Copilot and VS Code discovery.
The official MCP Registry stores a server manifest with the server name, description, version, repository and remote transport. CurrencyCore keeps that manifest in apps/mcp/server.json and publishes runtime discovery at /.well-known/mcp/server-card.json.
Client directories such as the Claude Connectors Directory, the ChatGPT plugin directory and the Google Connected Apps store add review, screenshots and one-click install. Those listings use the same remote URL and OAuth contract documented on this page, so a listing never changes the integration a developer already tested.
Common questions
Which AI clients work with CurrencyCore?
CurrencyCore works with Claude, ChatGPT, Cursor, VS Code, Gemini CLI, Windsurf, and any client that supports remote Streamable HTTP MCP with OAuth. The server URL is https://mcp.currency-core.com/mcp.
Do I need an API key to connect an agent?
No. The MCP server uses OAuth 2.1, so the client opens a browser where you sign in and choose a CurrencyCore organization. The resulting token is scoped to that organization and can be revoked from the client or the dashboard.
Is MCP included on the free plan?
Yes. MCP access is included on every plan, including Free. Each successful tool call counts as one API request against the organization's monthly quota. Analytics tools require Growth or above and return 403 on lower plans.
How is MCP usage billed?
One successful tool call equals one API request. MCP does not consume AI credits. Tool results include the billed count in _meta so an agent can reconcile usage.
Where is the machine-readable server metadata?
The server publishes a card at https://mcp.currency-core.com/.well-known/mcp/server-card.json, plus OAuth protected-resource metadata at /.well-known/oauth-protected-resource/mcp. The repository also carries a server.json manifest for registry publication.
Can I use the REST API instead of MCP?
Yes. Every MCP tool maps to a REST endpoint under https://api.currency-core.com/v1. Use the REST API for server-side jobs and MCP when an interactive agent should choose the tool.
