Overview

AI-generated overview

Lets an assistant generate presentation-ready charts in SVG and PNG across 14 or more chart types.

What you can do
Charta is a local MCP server that produces charts on demand. According to its registry description, it generates presentation-ready charts in SVG and PNG formats and supports 14 or more chart types. No individual tools are listed in the supplied manifest, so the exact tool names and inputs are not documented here.
When to use it
Worth adding when an assistant needs to turn data into chart images for slides, reports, or documents, and you want the output as SVG or PNG files rather than an interactive chart. It is a desktop-only local process, so it suits a single machine rather than a shared or hosted setup.
Requirements
Runs as a local process over stdio, installed from the npm package @charta/mcp, so Node.js and npm are needed on the machine. The manifest declares no authentication, environment variables, or headers. Desktop only; not available as a web executable.
Before you install
The manifest declares no credentials, environment variables, or headers, and no write, send, or delete behavior is described. The registry description gives no detail on where generated files are written or what data leaves the machine, so review the package before installing.

Installation

In SourceWeft

  1. Open Charta in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
