Q: What features does CoinGecko MCP server provide?

Retry logic with exponential backoff: Automatically retries transient failures by default (2 retries) with exponential backoff; configurable maxRetries.. Configurable timeouts: Default 1 minute timeout with per-request overrides; per-request timeout supported.. Comprehensive error handling: APIError family with specific error types for common HTTP errors (e.g., BadRequestError, AuthenticationError, etc.).. Raw Response access: Access the raw fetch Response via asResponse() and withResponse() helpers.. Type-safe request/response definitions: TypeScript definitions for all request parameters and responses, with hover documentation.. Flexible fetch customization: Support custom fetch implementations, fetchOptions, and proxy configurations for different runtimes.. Undocumented endpoints support: Make calls to undocumented endpoints or parameters; extra values pass through without runtime validation.. Configurable logging: Control log output via COINGECKO_LOG or logLevel; optional custom logger support.

CoinGecko MCP Server 2025: Features & Setup Guide

Overview

This repository provides a server-side TypeScript/JavaScript client for the CoinGecko REST API. It offers a typed interface for accessing price and market data via the REST endpoints, with support for Pro API access and Demo API access via environment selection. Installation is via npm, and usage examples show creating a client with API keys and making requests such as retrieving simple price data. The library ships with TypeScript definitions for all request parameters and responses, and rich error handling through APIError subclasses (BadRequestError, AuthenticationError, PermissionDeniedError, NotFoundError, UnprocessableEntityError, RateLimitError, InternalServerError, APIConnectionError). Retries are automatic by default (2 retries with exponential backoff), and requests can be configured per-request or globally (maxRetries). Timeouts are configurable (default 1 minute). Raw response access is supported through asResponse() and withResponse(). Logging is configurable via COINGECKO_LOG or logLevel, and custom loggers are supported. It also enables undocumented endpoints and parameters, customizable fetch, and proxy support for Node/Deno/Bun environments.
