How do I use FastStats for Claude?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@FastStats for Claude make a dashboard showing how servers configure my plugin" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

FastStats for Claude

A Claude Desktop extension (MCP server) that lets Claude design, validate and publish FastStats charts and dashboards for your projects.

Ask things like "make a dashboard showing how servers configure my plugin" and Claude will read your project's metrics, design the charts, test each one against your real data, and save them.

Nothing broken gets saved. Every chart is checked against your project's fields and dry-run with FastStats' preview endpoint before it is created or updated.
Your edits are safe. Updates never overwrite a chart that changed since Claude read it, and deleting anything needs explicit confirmation.
Read-only mode hides every tool that writes, if you only want Claude to look.

Install

Download faststats-mcp.mcpb from the latest release.
Double-click it, or drag it into Claude Desktop under Settings → Extensions, then click Install.
Paste a FastStats API key when asked (create one on faststats.dev under Settings → API keys). It's stored in your system keychain and only sent to FastStats.

That's it: no Node.js, cloning or building needed. Claude Desktop runs the extension with its built-in Node runtime.

Settings

Setting
FastStats API key	Required. Only projects this key can access are visible to Claude.
Default project	Optional slug or id (e.g. `my-plugin`) used when you don't name a project.
Read-only mode	Hides create, update and delete tools.

Change them any time under Settings → Extensions → FastStats.

Tools

Tool	Writes
`get_guide`		Spec format, step reference, semantics, recipes
`list_projects`		Projects your key can access
`get_project_context`		Fields (built-in and custom metrics), dashboards, charts
`get_chart`		A chart as an editable spec
`preview_chart`		Validates and dry-runs a spec, returns a data sample
`list_event_markers`		Marker collections or their markers
`list_data_sources`		Custom metrics, optionally with event coverage and observed json paths
`check_project_data`		Whether the project is receiving data
`get_anomalies`		Metric health and incidents (spikes, shifts, gaps) with likely causes
`get_download_analytics`		Downloads per platform and version, plus linked listings
`search_download_providers`		Find a listing on Modrinth, Spigot, Hangar, Ore, CurseForge or GitHub
`create_chart`	✔	Previews first. Auto-placed on a 12-column grid.
`update_chart`	✔	Previews first. Never overwrites newer edits made in the FastStats UI.
`delete_chart`	✔	Requires explicit confirmation

`create_event_marker`	✔	e.g. releases to overlay on time series

`update_data_source`	✔	Refuses to rename a referenceId that charts use unless forced
`delete_data_source`	✔	Requires explicit confirmation; refuses while charts use it unless forced

How charts are described

Claude writes charts in a compact series spec (datasource → filter → groupBy → aggregate …), and the extension compiles it into FastStats' flow graph:

{
  "name": "Storage backends",
  "chartType": "pie",
  "outputs": [{
    "name": "Servers",
    "steps": [
      { "datasource": "internal:server_count" },
      { "groupBy": "storage.method" },
      { "aggregate": "count" },
      { "limit": 8, "groupOthers": true }
    ]
  }],
  "visual": { "pie": { "style": "donut", "showTotal": true } }
}

Nested keys of JSON metrics (like storage.method above) work as dot paths. See src/resources/guide.md for the full format and docs/FLOW_SCHEMA.md for the reverse-engineered FastStats schema.

Other MCP clients

The server is a single file, so any stdio MCP client can run it. Build it (see below), then point your client at dist/index.js:

{
  "mcpServers": {
    "faststats": {
      "command": "node",
      "args": ["C:\\path\\to\\faststats-mcp\\dist\\index.js"],
      "env": { "FASTSTATS_API_KEY": "your-key" }
    }
  }
}

env	default
`FASTSTATS_API_KEY`	required	Sent as `x-api-key`. Never logged or returned.
`FASTSTATS_DEFAULT_PROJECT`	none	Slug or id used when a tool call omits `project`.
`FASTSTATS_READ_ONLY`	`false`	`true` hides every tool that writes.
`FASTSTATS_BASE_URL`	`https://api.faststats.dev`

Development

Requires Node.js 22+.

npm install
npm run build          # bundles to dist\index.js (self-contained)
npm test               # unit tests (compiler, round-trip on real charts, grid, client, manifest)
npm run test:contract  # checks hard-coded enums against the live OpenAPI spec
npm run typecheck
npm run pack           # build + validate manifest + create faststats-mcp.mcpb
npm run inspect        # MCP Inspector against dist\index.js

To try a local build in Claude Desktop, run npm run pack and install the resulting faststats-mcp.mcpb.

Releasing

Bump version in both package.json and manifest.json (a test fails if they differ), and commit.
Publish a GitHub release whose tag is that version, e.g. 0.2.0 (no v).

GitHub Actions runs the checks, builds faststats-mcp.mcpb and attaches it to the release, so the download link above always points at the latest version.
