DART

You can extend Claude with DART-MCP to analyze and visualize corporate financial data through the DART API. This MCP connects Claude to the DART data source, enabling structured financial insights, detailed analyses, and visualizations directly in your conversations.

How to use

You use a Claude desktop client configured to run the DART-MCP server locally. After you set up the integration, ask Claude to fetch data from the DART API and perform financial analyses. You can request major financial trends, department-level sales breakdowns, and valuation-oriented metrics such as discounted cash flow. Claude will query the DART API and return analyzed results, including visualizations created via Claude. If you need to adjust inputs, specify the company name using its official listing name and request quarterly or annual figures as needed.

## Configuration and usage notes

Only official company names (as listed) should be used when querying data. The MCP currently targets KOSPI/KOSDAQ listings. Real-time price data or market capitalization may be added in future updates, but are not part of the current MCP capabilities. You should provide a valid DART API key and ensure Claude can reach the DART API endpoints.

## Examples of capabilities

- Major financial analysis: summarize revenue and operating income trends by quarter or year for a given company.

- Detailed financial analysis: drill into line items, margins, and drivers behind variances.

- Segment/Business unit analysis: breakdown of revenue by business segment or subsidiary where available.

- Visualization: generate charts and graphs to illustrate revenue, profit, or cash flow trends.

- Valuation support: apply financial metrics such as DCF using data from the DART API for informed assessments.

## Security and usage cautions

Keep your DART API key secure and do not share it in public channels. Use the MCP only with officially listed company names and verify the scope of data you request. Remember that financial data may have limitations or delays depending on the source.
