What is the MCP MCP server?

MCP MCP server exists for a simple reason — assistants are far more useful when they can act on MCP directly instead of describing what you should do. An MCP server that provides OpenDart API.

What you get

Tips for getting started: 1. Ask questions, edit files, or run commands. 2. Be specific for the best results. 3. Create GEMINI.md files to customize your interactions with Gemini. 4. /help for more information.

What the assistant can call

Once MCP is connected, these are the calls the assistant has available:

  • find_fnguide_data — find_yahoofinance_data
  • get_yahoofinance_fundamentals — save_fundamentals_data_to_gcs
  • get_animal_details — get_animals_by_species

Setting it up

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Configuration and credentials

You will need 3 environment variables: GOOGLE_CLOUD_PROJECT, PROJECT_NUMBER, ID_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Choosing this one

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP's toolset — find_fnguide_data, get_yahoofinance_fundamentals, get_animal_details — is a fair guide to whether it matches your workflow. It is maintained by kcw2034-sayouzone; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp mcp server does with a few real requests.

Frequently asked questions

It connects MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (find_fnguide_data, get_yahoofinance_fundamentals, get_animal_details) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP directly.
