SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? ElevenLabs MCP tools fail when the ELEVENLABS_API_KEY environment variable is missing or invalid, and users often do not know where to obtain a key or how to store it correctly. This Skill walks through detecting an existing key, validating it against the ElevenLabs API, and persisting a working key to a .env file. ## Core Features & Use Cases - Existing Key Detection: Checks the environment and .env file for ELEVENLABS_API_KEY before asking the user for anything, avoiding redundant setup. - Key Validation: Verifies the key by calling GET https://api.elevenlabs.io/v1/user with the xi-api-key header, distinguishing valid keys from expired or malformed ones. - Guided Setup and Persistence: Directs the user to the ElevenLabs API keys page, then writes or replaces the ELEVENLABS_API_KEY line in .env after successful validation. - Use Case: An ElevenLabs text-to-speech tool call fails with an authentication error; invoke this Skill to confirm whether a key exists, validate it, and store a working replacement. ## Quick Start Set up my ElevenLabs API key so the ElevenLabs MCP tools can authenticate.

FAQPage Schema
How do I set up an ElevenLabs API key for MCP tools?▼

Create a key at https://elevenlabs.io/app/settings/api-keys, copy it immediately since it is shown only once, and provide it when prompted. The key is validated against the ElevenLabs API and stored as ELEVENLABS_API_KEY in a .env file.

How to check if my ElevenLabs API key is already configured?▼

The setup flow first checks the current environment and then the .env file for ELEVENLABS_API_KEY. If found, it validates the key with a GET request to https://api.elevenlabs.io/v1/user using the xi-api-key header before doing anything else.

Why do ElevenLabs tools fail with authentication errors?▼

Failures typically mean ELEVENLABS_API_KEY is missing from the environment and .env, or the stored key is invalid or expired. Re-running the setup validates the existing key and replaces it if validation against the ElevenLabs API fails.

Where is the ElevenLabs API key stored after setup?▼

The key is saved as ELEVENLABS_API_KEY=<key> in a .env file. If that line already exists it is replaced; otherwise a new line is appended.

What permissions does the ElevenLabs API key need?▼

If the key has the User permission set to Read, the setup flow can automatically verify it works by calling the /v1/user endpoint. Keys without that permission cannot be validated by this flow.
