Install the Tako plugin from the OpenAI plugin directory, then search the live web and Tako’s graph of licensed data inside ChatGPT or Codex.
The Tako plugin searches the live web and a graph of licensed, continuously updated data in the same call. Ask in plain language, and Tako answers with the figure, its source, and a chart. Web search reaches the rest, so one question can draw on both.Install once from the OpenAI plugin directory. One listing covers both ChatGPT and Codex. Sign in with your Tako account when prompted, and the plugin creates its own API key, so you never paste one.
Go to Tako in the OpenAI plugin directory. The directory works on every ChatGPT plan, including the free tier, and doesn’t require Developer mode.

Install and sign in
Click +, then approve the Tako sign-in. Approving creates an API key for you. Each host you connect gets its own key, which you can revoke at tako.com/console/api-keys.
Installing Tako from the plugin directory, approving the sign-in, and attaching it in a new chat.

Start a new chat or Codex session
Skills load when a session starts, so an open session doesn’t see them. Start a new chat, then ask for a figure.The install sits on your OpenAI account, so Codex picks it up too. Sign in to Codex with the same account, then start a new codex session.
The plugin includes Tako’s ChatGPT tool set and its skills, so there’s nothing else to set up. Two heavier tools, tako_agent and tako_search_advanced, aren’t in the listing. To reach those, to connect a different client, or to add Tako by hand, see MCP server.
Searches Tako’s data graph and the live web in one call. Returns knowledge cards, each with a headline value and an interactive chart, plus web results.
tako_available_data
Reports what data Tako holds for an entity or metric, and returns the canonical name to search on. Never charged.
tako_contents
Fetches a card’s data rows or a web page’s text, up to 10 URLs per call.
tako_graph_related
Lists what a graph node connects to: its metrics, entities, competitors, industry, and sources. Never charged.
tako_visualize
Builds a Tako chart from data you supply. Warning: the card is public and permanent, so don’t send sensitive data. The model confirms before it publishes.
ChatGPT renders the chart inline. Codex is a terminal, so it returns the data and a link to the chart.
The tools work across everything Tako covers. Skills add depth in three domains. Each one tells the model which tool to call, how to shape the query, and how to report the result.

Skills load when a session starts, so start a new chat or codex session. If you added Tako as a custom connector, you have the tools but not the skills. Remove the connector, then install from the plugin directory to get both — two Tako connections give you two copies of every tool.
Tako asks you to sign in first
The ChatGPT surface, https://mcp.tako.com/mcp/chatgpt, requires a sign-in. Approve it once and the tools run. To try Tako without an account, add the https://mcp.tako.com/mcp endpoint in another client. See MCP server.
The tools don't appear
Restart the client so that it repeats the tools/list handshake. If a host stops authenticating, remove it and add it again to mint a new key. Tako keeps 10 MCP keys, so connecting an eleventh host removes the oldest.
tako_contents refuses a card
A search hits a rate limit
A signed-in connection uses your account’s limits. See pricing for your plan’s rates. To check coverage without spending credits, use tako_available_data or tako_graph_related.
