TakoData Tako MCP Tools (7)
tako_search
Find the data.** Fast search over Tako's curated graph and the live web. Four parameters — `query`, `sources`, `country_code`, `locale` — and no defaults of its own, so an omitted field takes the API's. Cards carry headline values, node ids and chart links; `tako_contents` reads the rows. The top r…
tako_available_data
Find what structured data exists** on an entity or metric in one free call — the exact metric name to search on, an `id` for graph traversal, and a ready-to-run `next_call`. Ambiguous names come back as candidates with a `kind`; `metric` doubles as the substring browse filter; `limit` widens the ca…
tako_contents
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
MCP Mermaid is categorized under Data Visualization and uses a local stdio subprocess. In contrast, TakoData Tako MCP belongs to Data Visualization using remote streaming HTTP/SSE transport. Select MCP Mermaid when you need capabilities focused on data visualization and TakoData Tako MCP when you require tools for data visualization.
Fetch what's behind result URLs (1-10 per call): a card's rows (billed per 1k rows) or a web page's text — pass `query` for only the matching passages. Requires a signed-in connection.
tako_graph_related
Explore a graph node: a map (each relation's key, total, first three names) or one paged relation — metrics, the entities a metric covers, competitors (`rel:competes_with`), memberships, sources. `q` is a substring filter. Free.
tako_search_advanced
The whole v3 search request body: per-source `count`, inline rows and `max_rows`, graph pins (`node_ids` + `strict`), web `include_domains` / `exclude_domains` / `category` / `snippet_max_chars` / `published_after` / `published_before`, `location`, `timezone`, `include_related`, and `effort: deep`.…
tako_agent
Tako's **Answer Agent**: multi-step research (~30–90s) across many retrievals, returning a synthesized answer plus chart cards.
tako_visualize
Author a Tako card from your own typed `components` (timeseries, bar, table, financial boxes…). It PUBLISHES: the card is public, permanent, and readable by anyone with the link. On by default on `/mcp/chatgpt`, the host that renders the widget inline.
