No Yahoo Finance MCP server yet? Build one in minutes

Record the Yahoo Finance 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 Yahoo Finance account.

  1. 1
    Record a Yahoo Finance action once

    Open the recorder and open a ticker on Yahoo Finance 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 Yahoo Finance 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

Yahoo Finance has no MCP server

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

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

Yahoo Finance MCP questions

Is there an official Yahoo Finance MCP server?
Yahoo Finance does not publish an MCP server. Writ lets you turn the Yahoo Finance 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 Yahoo Finance MCP tools I can install?
Record the Yahoo Finance 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 Yahoo Finance tasks, then return structured output your agent can use.
Does it work with Yahoo Finance login and 2FA?
Yahoo Finance quote pages are public; Writ renders them in real Chromium to capture quotes and figures that update live. Because each MCP tool is a real browser workflow, it runs inside your own authenticated Yahoo Finance session, with TOTP and mailbox-OTP two-factor handled by Personas.
Which MCP clients can use these Yahoo Finance 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 Yahoo Finance this way?
Collect Yahoo Finance 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.
