How to Use the DevCycle MCP in Cursor

Q: How do I configure the DevCycle MCP server in Cursor?

Create a .cursor/mcp.json file in your project root. Add the server details, save the file, and switch your chat to Agent mode. The tools load immediately.

Q: Will Cursor automatically toggle DevCycle flags?

Only if you tell it to. The agent can execute updatefeatureflagstatus, but it waits for your prompt. It won't randomly flip production switches while you write code.

Q: How does Cursor find my DevCycle projects?

The agent runs listdevcycleprojects to pull the IDs and names of everything in your account. You just mention the project name in your prompt, and it handles the routing.

Q: Can I use this DevCycle setup for multiple projects in Cursor?

Yes. You can define the MCP configuration globally in /.cursor/mcp.json instead of the project root. This makes the tools available across every repository you open.

Inject real DevCycle flag configurations straight into your code with Cursor.

Perplexity

Code against real DevCycle states

`get_feature_flag_details` pulls the actual JSON configuration of your flags while you write the implementation. Cursor reads the exact variable types and targeting rules, then generates the corresponding conditional logic in your codebase. You never have to switch tabs to check if a variable is a boolean or a string. The agent uses `list_feature_variables` to map out the current project definitions and writes the exact SDK calls you need.

Access SDK keys without leaving Cursor

`get_environment_sdk_keys` fetches the exact credentials for your current environment directly into your editor. When you set up a new local testing client, Cursor grabs the staging key and drops it into your `.env` file. It also maps out your infrastructure using `list_project_environments` and `get_project_details`. This MCP Server gives your agent the context to configure environment-specific initializations without you copying and pasting UUIDs.

Deprecate old code automatically

`search_feature_flags` tracks down flags that haven't changed in months. You ask Cursor to find stale toggles, and it cross-references the API response with your local files to identify dead code paths. Once you remove the code, the agent calls `update_feature_flag_status` to archive the flag in the dashboard. You handle the code deletion and the API state change in a single workflow.

Setup guide

Set up DevCycle 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 DevCycle 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 DevCycle transactions." If the MCP tools are loaded correctly, Cursor will call the DevCycle tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

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