Connect via MCP

Anthra speaks the Model Context Protocol over Streamable HTTP at /api/mcp. Any MCP-compatible client (Claude Desktop, Cursor, Claude Code, Continue, …) can authenticate with one of your personal access tokens and call Anthra’s tools.

Endpoint

URL:    https://anthra.vercel.app/api/mcp
Method: POST (JSON-RPC)
Auth:   Authorization: Bearer ant_live_…
Protocol revision: 2025-06-18

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on your OS:

{
  "mcpServers": {
    "anthra": {
      "url": "https://anthra.vercel.app/api/mcp",
      "headers": {
        "Authorization": "Bearer ant_live_…"
      }
    }
  }
}

Restart Claude Desktop. You should see anthra appear in the tools list with entries like create_book, generate_outline, write_chapter, and publish_book.

Claude Code

claude mcp add --transport http anthra \
  https://anthra.vercel.app/api/mcp \
  --header "Authorization: Bearer ant_live_…"

Cursor

In Cursor’s settings → Tools & Integrations → Add MCP Server:

{
  "mcpServers": {
    "anthra": {
      "url": "https://anthra.vercel.app/api/mcp",
      "headers": { "Authorization": "Bearer ant_live_…" }
    }
  }
}

What the model can do

The Anthra MCP exposes the same operations as the REST API. The model will:

• List, read, create, and update books (books:read, books:write).
• Generate outlines, write chapters, rewrite with a directive, and synthesize narration (generation:run).
• Publish books and toggle visibility (publish:write).
• Read account usage and reader analytics (account:read, analytics:read).

Tools that mutate or spend tokens are gated behind their scope — a key without generation:run can still let the model list and read your books but won’t allow generation.

Recommended scopes for a chat-only client

books:read
books:write
generation:run
publish:write

Add account:read and analytics:read if you want the model to reason about spend or reader behaviour.

See the full tool reference for every operation, its arguments, and which scope it requires.
