Compatible with every major AI agent and IDE
What is the Prowlarr (Indexers) MCP Server?
Connect your Prowlarr instance to any AI agent and take full control of your indexer management through natural conversation. This server allows you to orchestrate your Usenet and Torrent indexers without leaving your workspace.
What you can do
- Indexer Overview — List all configured indexers and retrieve detailed configurations for specific ones using their IDs.
- Health Monitoring — Instantly check the health status of all indexers to identify connection issues or failures.
- Configuration Management — Add new indexers, update existing settings, or remove indexers that are no longer needed.
- Schema Discovery — Fetch templates and required fields for various indexer types (Newznab, Torznab, etc.) to ensure correct setup.
- Pre-save Testing — Test indexer configurations before saving them to ensure credentials and URLs are valid.
How it works
- Subscribe to this server
- Enter your Prowlarr URL and API Key
- Start managing your indexers from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Home Lab Enthusiasts — Monitor and maintain your media automation stack without opening multiple web interfaces.
- Media Server Admins — Quickly troubleshoot indexer failures and update API keys or URLs on the fly.
- DevOps Engineers — Automate the provisioning and testing of indexer configurations via AI-driven workflows.

Every tool call from Mastra AI to the Prowlarr (Indexers) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How can I check if any of my indexers are currently down?
You can use the get_indexer_status tool. It retrieves the current health status of all configured indexers, highlighting any errors or connection issues.
What is the best way to add a new indexer without knowing the JSON structure?
First, run get_indexer_schema to see the templates for supported indexers. Once you have the correct fields, you can use add_indexer with the required data.
Can I verify my settings before applying them to an indexer?
Yes! Use the test_indexer tool. It allows you to test the connection and configuration of an indexer before saving it, preventing broken setups.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
