How to Use the Mastodon MCP in Cursor

Q: How do I add the Mastodon MCP Server to my Cursor project?

Create a .cursor/mcp.json file in your project root and add the server configuration. Once Cursor loads the MCP configuration, your AI agent can immediately use tools like verifycredentials to test your connection.

Q: Can I create new applications on my instance using this tool?

Yes, your Cursor agent can run createapp directly through the editor to register client credentials on your target instance. This makes setting up new development environments incredibly fast.

Q: How does Cursor protect my Mastodon OAuth credentials?

Your credentials reside in your local .cursor/mcp.json or environment files. Cursor passes these strictly to the local node process running the server, ensuring your Mastodon statuses and tokens remain private.

Build Fediverse integrations and test Mastodon API responses live inside your Cursor editor using this MCP Server.

Perplexity

Inject live Fediverse data into your Cursor workspace

This development-focused Mastodon MCP Server injects live Fediverse payloads directly into your active Cursor editor window using `get_home_timeline` and `get_status`. Stop writing code against outdated mock data. By seeing the exact Mastodon JSON structure your instance returns, you can write cleaner parsing logic inside Cursor. Your agent uses these live responses to generate accurate TypeScript profiles on the fly.

Automate code testing with live Mastodon actions

This testing-ready MCP Server executes write actions like `post_status` and `upload_media` directly from your Cursor workspace. You can test your application's write paths without leaving Cursor by telling the agent to run these real API calls. If a test post goes wrong, just have the Cursor agent run `delete_status` to clean up your instance. It speeds up your development loop because you don't have to switch to an external API client to verify your code's behavior.

Monitor instance health while you write code

This health-monitoring MCP Server lets your Cursor agent run `check_health` and `get_instance_info` to verify the state of your target server during debugging. When building tools for the Fediverse, instance uptime matters. You can also pull the server rules using `get_instance_rules` to ensure your automated posts comply with local policies inside Cursor. It keeps your development aligned with instance guidelines without manual checks.

Setup guide

Set up Mastodon MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Mastodon MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Mastodon transactions." If the MCP tools are loaded correctly, Cursor will call the Mastodon tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "mastodon-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about Mastodon MCP in Cursor

Create a `.cursor/mcp.json` file in your project root and add the server configuration. Once Cursor loads the MCP configuration, your AI agent can immediately use tools like `verify_credentials` to test your connection.

Yes, you can ask your Cursor agent to write a script that identifies inactive accounts and runs `unfollow_account` for each one. The agent executes the calls sequentially through the editor's terminal integration.

The server passes standard rate limit headers back to Cursor. If you run heavy tools like `get_public_timeline` repeatedly, your Cursor agent will see the limit warnings and can pause your active scripts.

Yes, your Cursor agent can run `create_app` directly through the editor to register client credentials on your target instance. This makes setting up new development environments incredibly fast.

Your credentials reside in your local `.cursor/mcp.json` or environment files. Cursor passes these strictly to the local node process running the server, ensuring your Mastodon statuses and tokens remain private.
