Narrador MCP Server

narrador MCP server

narrador turns documents and X (Twitter) posts into natural narrated audio with word-level timestamps. Upload PDFs, Word, EPUBs or text, pick a voice (or let narrador files choose one from the document language), start conversion jobs, check status and download audio with synced timings. narrador X turns posts into audio the same way. Sign in with OAuth at narrador.io, or use a product API key.

Remote Model Context Protocol server for narrador. It lets AI agents (Claude, Cursor, VS Code, Windsurf, ChatGPT and any MCP client) use narrador files and narrador X.

• narrador files: PDF, Word, EPUB and other documents → audio with word-level timings.
• narrador X: X/Twitter posts → audio.

Repository: https://github.com/narrador-io/narrador-mcp

This repository only holds the public listing (server.json), registry metadata (glama.json) and documentation. The server is hosted by narrador; there is nothing to install locally.

Credits

Usage is metered in narrador credits (see get_account). Jobs and generations consume credits when they run. There are no subscriptions—buy credits in the narrador web app and check balance before calling tools that spend credits.

Tools (7)

get_account

No parameters. Returns user, app (API key product or null for OAuth), products (files and/or x), and credits (totalAvailable and per-bucket balances). Does not consume credits.

list_voices

Each voice includes id, name, tier (standard or cheaper), defaultAccent, isPublic, description, and sampleUrl (https://api.narrador.io/v1/voices/{id}/sample, a neutral sample redirect that does not require an API key). A legacy provider field may mirror tier and is deprecated—use tier.

create_files_job

Provide either text or fileId, not both.

When voiceId and accent are omitted, narrador detects language from the document (en-us, es-es, pt-br). Very short or undetectable text falls back to en-us. It then picks a standard tier voice for that language, or a cheaper tier voice if none—deterministic catalog order. If the detected language has no supported voice, the job ends with failed_file_processing; pass voiceId and accent explicitly.

Returns jobId. Poll with get_files_job, then call get_files_result when status is completed. Consumes credits.

get_files_job

Returns status (e.g. processing, completed, failed), progressPercentage, and audioId when ready.

get_files_result

Returns audioUrl, audioId, duration, and wordTimings (word, startTime, endTime).

generate_x_audio

Returns generationId, audioUrl, duration, and wordTimings when ready (often immediately). Poll get_x_generation if needed. Consumes credits.

get_x_generation

Returns the same audio metadata as a successful generate_x_audio call. Only generations linked to your account are returned; other ids respond with generation not found.

Authentication

OAuth (recommended). Add the URL https://api.narrador.io/mcp to your client. The client discovers the authorization server (https://narrador.io/api/auth); sign in on narrador.io and approve access. Scopes: narrador:files, narrador:x.

API key. Create a key in the narrador web app and send it as Authorization: Bearer <key> or x-api-key: <key>. Keys are scoped per product:

Connect

Claude Desktop

Settings → Connectors → Add custom connector → URL https://api.narrador.io/mcp → Connect, then complete OAuth on narrador.io.

Cursor

Project (.cursor/mcp.json) or user (~/.cursor/mcp.json):

{
  "mcpServers": {
    "narrador": { "url": "https://api.narrador.io/mcp" }
  }
}

With an API key:

{
  "mcpServers": {
    "narrador": {
      "url": "https://api.narrador.io/mcp",
      "headers": { "Authorization": "Bearer nrd_files_..." }
    }
  }
}

VS Code

.vscode/mcp.json:

{
  "servers": {
    "narrador": { "type": "http", "url": "https://api.narrador.io/mcp" }
  }
}

Claude (claude.ai)

Same as Claude Desktop: Add custom connector with https://api.narrador.io/mcp.

Claude Code

claude mcp add --transport http narrador https://api.narrador.io/mcp

Windsurf (~/.codeium/windsurf/mcp_config.json)

{
  "mcpServers": {
    "narrador": { "serverUrl": "https://api.narrador.io/mcp" }
  }
}

Any other client

Point it at https://api.narrador.io/mcp (Streamable HTTP). If the client has no OAuth support, send an API key in the Authorization header.

Example prompts

• "Check my narrador credits, then convert this PDF to audio with narrador files."
• "List standard-tier voices for narrador files in Spanish, then create a job for this text."
• "Turn this X post into audio with narrador X: https://x.com/…/status/…"
