Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account junct-bot for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A hosted MCP server exposing 30 CoinMarketCap tools for crypto data, metrics and on-chain analytics, with no authentication required.

What you can do: Query cryptocurrency market data and metrics through CoinMarketCap endpoints, including on-chain analytics, via roughly 30 tools that each map to a real API endpoint.
When to use it: Useful when an assistant needs cryptocurrency prices, market metrics or on-chain data and you want a hosted, key-free connection rather than building your own API integration.
Requirements: A remote Streamable HTTP endpoint; no API key, account or environment variables are declared. Network access to the hosted endpoint is needed.

Before you install

The server is third-party hosted and free with no auth, so requests and queries pass through an external service; treat returned market data as informational, not financial advice, and verify figures before relying on them.

Installation

In SourceWeft

Open Coinmarketcap Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.junct-bot%2Fcoinmarketcap-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
