No CoinMarketCap MCP server yet? Build one in minutes

Record the CoinMarketCap task once, or describe it to an AI session, and Writ turns it into an MCP tool your agent can call, taking real actions on your own CoinMarketCap account.

  1. 1
    Record a CoinMarketCap action once

    Open the recorder and open a coin on CoinMarketCap in a real browser. Writ captures the steps, login and 2FA included, into a workflow.

  2. 2
    Publish it as an MCP tool

    One click exposes the workflow as an MCP tool with a typed input schema, alongside a REST endpoint. Your agent picks it by its description.

  3. 3
    Call it from any MCP client

    Point Claude Desktop, Claude Code, Cursor, or any MCP client at your Writ server. The CoinMarketCap tool acts on your own account and returns structured output.

Browse supported MCP clients, see what's possible on workflows, or search for another site. Free to start. See pricing.

why

CoinMarketCap has no MCP server

Read-only website-to-MCP tools can summarize a CoinMarketCap page, but they can't do anything on it. Writ turns the CoinMarketCap workflows you build into MCP tools your agent calls to take real actions (search, extract, submit), authenticated, on your own CoinMarketCap account.

Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.

CoinMarketCap tools your agent can call

Each tool is a real CoinMarketCap workflow with a typed input schema and structured output. Your agent picks the right one by its description.

CoinMarketCap MCP questions

Is there an official CoinMarketCap MCP server?
CoinMarketCap does not publish an MCP server. Writ lets you turn the CoinMarketCap workflows you build (recorded, described, or discovered) into MCP tools your agent can call. They take real actions, not just read page text.
Are there ready-made CoinMarketCap MCP tools I can install?
Record the CoinMarketCap task once in the recorder, or describe it to an AI session, then publish it. Writ exposes it as both an MCP tool and a REST endpoint, usually in minutes.
How is this different from a read-only website-to-MCP tool?
Most website-to-MCP tools are readability crawlers that return page text. Writ tools act and transact: they log in, fill forms, click, extract, and complete multi-step CoinMarketCap tasks, then return structured output your agent can use.
Does it work with CoinMarketCap login and 2FA?
CoinMarketCap pages are public; Writ renders them in real Chromium to capture live prices and rankings that update continuously. Because each MCP tool is a real browser workflow, it runs inside your own authenticated CoinMarketCap session, with TOTP and mailbox-OTP two-factor handled by Personas.
Which MCP clients can use these CoinMarketCap tools?
Any MCP-compatible client: Claude Desktop, Claude Code, Cursor, Windsurf, and others. Point the client at your Writ MCP URL and authenticate with a wt_ key (or a csk_ consumer key for downstream callers).
Is it allowed to use CoinMarketCap this way?
Collect CoinMarketCap data you have the right to access and respect its Terms of Use and rate limits. Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.
