MCP

Connect your AI assistant to OHLC with Model Context Protocol (MCP). Query stock data and get help with API endpoints, parameters, authentication, and errors in the same conversation.

1. Add OHLC to your assistant

   In Claude, open Connectors (under Customize or Settings) and add a custom connector with this URL. Leave the OAuth Client ID and secret blank.

   Server URL Copy

   https://api.ohlc.io/mcp

2. Sign in and allow access

   Click Connect, sign in to OHLC, and approve access to your workspace. You do not need to create or copy an API key. MCP is included on Developer, Pro, Commercial, and Scale. Manage your plan.

3. Verify the connection

   Save the server and refresh your client’s tools. You should see tools such as get_quotes, get_news and get_api_documentation. Try: “Explain the OHLC quotes endpoint and its parameters.” Then ask: “Get the latest available quote for XNAS:AAPL.” Data access depends on your workspace’s plan and available coverage.

Connected applications

Disconnecting immediately removes this application’s access. You can connect again from your assistant.

What your assistant can do

One tool per data endpoint

Quotes, prices and bars, fundamentals, filings, news, earnings, financial statements, estimates, ownership, options, economic data and more, each as its own tool such as get_quotes, get_news or get_earnings. Prices may be delayed; preserve the returned licensing notices.

get_api_documentation

Discover REST endpoints, read parameter and response schemas, and explain authentication, pagination, errors, limits, and WebSocket behavior. Ask for a topic or an exact endpoint such as /v1/quotes.

Troubleshooting

401: Reconnect your application, or check your API key. 403: Check your paid plan and workspace access. API-key connections also enforce key scopes and IP allowlists. 429: Wait for the Retry-After interval. REST and MCP share account limits, including documentation calls.

Opening the URL in a browser is not a connection test. Use an MCP client to initialize the server and list its tools. This page provides configuration; connection status is shown in your client.
