Common questions
Is chartlink safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: CHARTLINK_API_KEY, Authorization
Does it run on my computer or in the cloud?
Either way works: install it on your computer or connect to the cloud version.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, Rystic

chartlink-mcp
A stdio bridge to the chartlink MCP server, for clients that only launch local stdio servers. Charts, maps and tables with live-updating embed links: https://chartlink.app
{"mcpServers": { "chartlink": { "command": "npx", "args": ["-y", "chartlink-mcp"], "env": { "CHARTLINK_API_KEY": "viz_..." } } } }
No key yet? curl -X POST https://chartlink.app/api/signup returns a workspace and its key — no account. The key is shown once.
Without a key the bridge still starts and lists every tool, so you can look before you sign up; each tool call then answers with the signup step instead of running.
If your client speaks HTTP MCP, skip this package and connect directly: https://chartlink.app/mcp with Authorization: Bearer viz_....
By default the server exposes the template path — nine tools: find a template by need, read its contract, dry-run your data, create from it with your data and a few knobs, publish, hand back the links. The whole engine (every chart type, the full settings schema, brands, data sources) is behind CHARTLINK_MCP_URL=https://chartlink.app/mcp?full=1.
The manual your agent should read first: https://chartlink.app/llms.txt (the templates and the four-step loop); the full engine manual is https://chartlink.app/llms-full.txt.
