Financial Datasets

Implements the Model Context Protocol (MCP) interface to expose a standardized set of financial data tools that AI assistants like Claude can invoke through structured tool calling. The server acts as a bridge between Claude's tool-calling mechanism and the Financial Datasets API, translating natural language requests into parameterized API calls and returning structured financial data. This architecture eliminates the need for direct API integration in the client application and provides Claude with a declarative tool schema for each financial endpoint.

Retrieves structured financial statements (income statements, balance sheets, cash flow statements) for a given company ticker across multiple reporting periods, with configurable period type (annual/quarterly) and result limiting. The implementation queries the Financial Datasets API endpoint for each statement type and returns parsed JSON containing line items like revenue, expenses, assets, liabilities, and cash flows. Supports temporal filtering via period parameter to focus on specific fiscal years or quarters.

Fetches current stock prices and historical price data for a given ticker with configurable time ranges and aggregation intervals (daily, weekly, monthly). The server queries the Financial Datasets API to retrieve OHLCV (open, high, low, close, volume) data and returns structured JSON with timestamp, price, and volume information. Supports both point-in-time queries (current price) and time-series queries (historical prices with from_date/to_date filtering).

Retrieves recent news articles and market sentiment data for a given company ticker from the Financial Datasets API, with configurable result limiting to control the number of articles returned. The server queries the news endpoint and returns structured JSON containing article metadata (headline, source, publish date, summary) that Claude can analyze for sentiment or relevance. Supports filtering by ticker to focus on company-specific news rather than broad market news.

Provides cryptocurrency market data capabilities including listing all available cryptocurrency tickers in the Financial Datasets catalog and retrieving current/historical prices for crypto assets. The server exposes three crypto-specific tools: get_available_crypto_tickers (returns list of supported tickers), get_current_crypto_price (returns current price for a ticker), and get_crypto_prices (returns historical OHLCV data with date range filtering). Crypto data is sourced from Financial Datasets and supports the same interval-based aggregation as stock prices.

Implements server-side validation of tool parameters (ticker symbols, date ranges, period types, limits) before querying the Financial Datasets API, with structured error responses that Claude can interpret. The MCP server validates inputs against expected types and constraints (e.g., from_date must be before to_date, limit must be positive integer) and returns descriptive error messages when validation fails. This prevents malformed API calls and provides agents with clear feedback for retry logic.

Configures the Financial Datasets MCP server to run as a stdio-based subprocess that Claude Desktop can invoke, enabling seamless tool integration without manual API management. The server implements the MCP protocol's stdio transport layer, allowing Claude Desktop to spawn the server process, send tool invocation requests via stdin, and receive responses via stdout. Configuration is managed through Claude Desktop's config file (typically ~/.claude/config.json on macOS/Linux), which specifies the server command and environment variables (API key).

Enables Claude to autonomously chain multiple financial data tool calls to perform complex analysis workflows (e.g., fetch income statement → calculate ratios → retrieve news → assess sentiment). The MCP server provides individual tools that Claude can invoke sequentially based on its reasoning, allowing the agent to decide which data to fetch next based on previous results. This capability leverages Claude's native tool-calling and planning abilities without requiring explicit workflow orchestration logic in the server.
