Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "file-ai": {
      "command": "npx",
      "args": [
        "-y",
        "@flyfish-dev/file-ai"
      ]
    }
  }
}

Run this in your terminal

claude mcp add file-ai -- npx -y @flyfish-dev/file-ai

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "file-ai": {
      "command": "npx",
      "args": [
        "-y",
        "@flyfish-dev/file-ai"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "file-ai": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@flyfish-dev/file-ai"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is File AI 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

File AI

Read-only document awareness MCP server for agents. File AI uses Flyfish File Viewer core as the source of truth for format recognition, then turns local files into a stable profile, anchors, blocks, chunks, outline, search results, and contextual snippets so an agent can understand document content without reverse-engineering PDF, OOXML, spreadsheet, email, or archive internals.

MCP Registry name: io.github.flyfish-dev/file-ai

Install

Use it directly with npx:

npx -y @flyfish-dev/file-ai

Or install it globally:

npm install -g @flyfish-dev/file-ai

file-ai --transport stdio

MCP Client Config

Stdio:

"mcpServers": { "file-ai": { "command": "npx", "args": ["-y", "@flyfish-dev/file-ai"] } } }

Streamable HTTP:

npx -y @flyfish-dev/file-ai --transport http --host 127.0.0.1 --port 8765

Endpoint:

http://127.0.0.1:8765/mcp

Tools

doc_analyze: parse a local file and cache a document index.
doc_read: read blocks, chunks, or anchors from an existing index or path.
doc_search: search cached content with source anchors.
doc_context: retrieve nearby blocks around an anchor or query.
doc_list_formats: list File Viewer core registry formats, all supported extensions, renderer capabilities, and File AI extractor coverage.

Resources

doc://{indexId}/profile
doc://{indexId}/outline
doc://{indexId}/chunks

Supported Files

File AI recognizes formats through @file-viewer/core/headless, currently covering 206 registered extensions. profile.format is therefore aligned with the same renderer selection used by Flyfish File Viewer.

Content extraction is a separate layer. File AI provides structured awareness for text/code/Markdown/JSON, PDF text, DOCX, XLSX/CSV, PPTX, EML, and archive manifests. Other File Viewer renderer-only formats such as CAD, 3D, media, image, geospatial, drawing, ebook, and data assets are still recognized in profile.format; when no structured text extractor exists yet, File AI returns a profile plus best-effort metadata/text and explicit warnings in profile.warnings and profile.extraction.

Every content block carries an anchor such as a page, slide, worksheet, row range, nested path, or byte/text location. Agents should cite returned anchorId values when making document-grounded claims.

Development

pnpm install

pnpm build pnpm test pnpm validate:skill

Run locally:

pnpm dev -- --transport stdio

pnpm dev -- --transport http --port 8765

Publishing

The package includes:

npm metadata for @flyfish-dev/file-ai
MCP Registry metadata in server.json
GitHub Actions workflow .github/workflows/publish-mcp.yml

Release flow:

git tag v0.1.0

git push origin v0.1.0

The workflow publishes the npm package first, then publishes io.github.flyfish-dev/file-ai to the official MCP Registry through GitHub OIDC. The repository must have an NPM_TOKEN secret that can publish @flyfish-dev/file-ai.

The server is read-only. It does not mutate source documents.
