Semiotic is a React data visualization library that includes charts, network graphs, geographic maps, realtime charts, and coordinated views. It also provides an MCP server and schema/validation tooling so AI assistants can generate and render chart code reliably.
From the registry: Render React data visualizations from JSON. 43 chart types; validate, diagnose, suggest tools.

Please install the `semiotic` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Node.js and npm** — Install Node.js and npm so you can run the MCP server via npx. (https://nodejs.org/)
Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["semiotic-mcp"]
Note: README shows local stdio usage with `npx semiotic-mcp` and explicitly says no API keys or authentication are required. An optional HTTP mode is mentioned for inspectors/web clients via `npx semiotic-mcp --http --port <port>`, but the primary MCP client configuration shown is stdio.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Web scraping with stealth HTTP, real browsers, and Cloudflare bypass. CSS selectors supported.
