Perplexity

Inject live stock quotes into Cursor

The `get_stock_quote` tool gives your Cursor Agent the ability to fetch live stock prices while it writes your trading algorithms. Your agent pulls real-time bid, ask, and close prices to test your execution logic against actual market conditions. This MCP Server removes the need for hardcoded mock data in your workspace. Cursor calls the tool inline, letting the AI generate code that processes real, live numbers.

Inspect company profiles inside Cursor

The `get_company_profile` tool retrieves sector classification, share outstanding numbers, and exchange details directly into your Cursor editor. Your agent uses this raw metadata to build accurate database schemas or API models. You do not need to guess the shape of the incoming payload. The MCP Server feeds the exact JSON structure to Cursor, allowing the editor to auto-complete your typed interfaces.

Search symbols while writing code in Cursor

The `search_symbols` tool allows your Cursor agent to resolve company names to tickers without stopping your coding flow. If you are building a dashboard, the agent queries the endpoint to map user inputs to valid symbols. Running this tool directly in Cursor keeps your focus on the codebase. Your editor handles the lookup behind the scenes, preventing broken API requests from typos.

Setup guide

Set up Finnhub MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Finnhub MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.

Common questions about Finnhub MCP in Cursor

Add the server to your ~/.cursor/mcp.json file for global access, or create a project-specific config. Provide your API key in the environment variables, and Cursor Agent will start calling the tools.

Yes, when you ask Cursor to write a script using live market data, it calls `get_basic_financials` or other endpoints to fetch the exact numbers it needs to write the code.

Your agent runs the `list_crypto_symbols` tool to get supported tokens for your target exchange. This allows Cursor to generate accurate crypto-tracking scripts without manual verification.

It acts as an interactive bridge. Instead of writing boilerplate code to test the API, you use the tools to see the raw data shape inside Cursor before committing the code to your repo.

Yes, your credentials reside in your local Cursor configuration or secure environment variables. The MCP Server runs locally to process your stock quotes and financial metrics, ensuring they are never shared with public LLM training sets.
