How do I get DevCycle API credentials?

Log in to your DevCycle dashboard, navigate to **Settings > Organization > API Management**, and create a new Client ID and Client Secret.

Can the agent toggle feature flags?

Yes, you can use the update_feature_flag_status tool to set a flag to 'active' or 'archived' directly from the agent.

Does the integration show SDK keys?

Yes, the get_environment_sdk_keys tool allows the agent to retrieve the specific identifiers needed for your web, mobile, or server-side SDKs.

About DevCycle MCP Server

Integrate DevCycle, the modern feature flag and experimentation platform, directly into your AI workflow. Manage your feature flags across projects, monitor staging and production environments, and audit targeting rules and variations using natural language.

Cursor's Agent mode turns DevCycle into an in-editor superpower. Ask Cursor to generate code using live data from DevCycle and it fetches, processes, and writes. all in a single agentic loop. 10 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

What you can do

Feature Flag Management — List, search, and retrieve detailed configuration for all your feature flags.
Environment Oversight — Monitor project environments, retrieve SDK keys, and track deployment statuses.
Variable & Variation Tracking — List all defined variables and their variations to ensure technical consistency.
Operational Control — Update feature flag statuses (active/archived) directly via chat.

The DevCycle MCP Server exposes 10 tools through the Vinkius. Connect it to Cursor in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use Cursor with the DevCycle MCP Server

Cursor AI Code Editor provides unique advantages when paired with DevCycle through the Model Context Protocol.

Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context

Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards

MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment

VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

DevCycle + Cursor Use Cases

Practical scenarios where Cursor combined with the DevCycle MCP Server delivers measurable value.

Code generation with live data: ask Cursor to generate a security report module using live DNS and subdomain data fetched through MCP

Automated documentation: have Cursor query your API's tool schemas and generate TypeScript interfaces or OpenAPI specs automatically

Infrastructure-as-code: Cursor can fetch domain configurations and generate corresponding Terraform or CloudFormation templates

Test scaffolding: ask Cursor to pull real API responses via MCP and generate unit test fixtures from actual data

DevCycle + Cursor FAQ

Common questions about integrating DevCycle MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
