# BFrost > BFrost is a local desktop app for macOS that manages MCP (Model Context Protocol) server and Agent Skill configuration across 15 AI agents, including Claude Code, Claude Desktop, Codex, Cursor, VS Code, Windsurf, Factory Droid, and Grok Build. It works entirely on the user's machine: no account, no cloud service, no telemetry, no required network connection.

It discovers the MCP servers and Agent Skills in the native configuration files those agents already use, shows them in one inventory grouped per agent, and edits them with previews, timestamped backups, and conflict detection. It never runs servers and never sends configuration anywhere. ## Supported agents Fully managed (MCP servers can be added, edited, removed, enabled, disabled, and removed): - Claude Code - Claude Desktop - Codex - Factory Droid - Grok Build - Cursor - Cline - Devin CLI - OpenCode - Gemini CLI - Antigravity IDE View-only (shown in the inventory, never edited): - VS Code / Copilot - Windsurf - Trae - Pi ## Platform coverage All 15 agents support user-scope configuration. Shared-project scope is supported by every managed agent except Claude Desktop and Windsurf. A native on/off toggle field exists for Claude Code, Codex, Factory Droid, Grok Build, Cursor, Cline, Devin CLI, OpenCode, Gemini CLI, and Antigravity IDE. VS Code, Windsurf, Trae, and Pi have no in-file toggle, so BFrost supports removal there instead of a switch. ## What you can do - See every configured MCP server across all 15 agents and registered project folders in one list, grouped per agent with scope, source file, and enabled state. Filter by agent or scope and search by name. - Discover, inspect, create, copy, share (linked copy), and trash Agent Skills across Claude Code, Codex, OpenCode, and Cursor. - Detect repeated servers: identical copies, same command with different settings, and same name with different servers. One-click cleanup keeps the first server and removes the rest, after a backup. Secret values are never displayed. - Add, edit, remove, enable, or disable servers through a form with save-location selection, editable environment variables and headers, and a configuration preview before anything is written. - Save a local copy of any writable server and copy it to another agent's config file, with a preview, a backup, and a conflict check. - Register project folders so project-level configuration appears next to the user setup. ## Safety model - Every write is atomic: a temporary file is written and renamed, so a crash cannot leave a half-written config. - The previous version of every edited file is preserved with a timestamp. Restoring any backup is one click. - If a file changed outside BFrost, it refuses to overwrite and shows exactly what differs. - All mutations are concurrency-checked against the file version read when the dialog opened. - Unknown or unsupported entries are preserved as read-only, never deleted or rewritten implicitly. - BFrost never launches a local executable or contacts a remote endpoint unless the user explicitly tests one, never sends configuration contents or secrets to any service, and never makes cross-agent writes without a preview and confirmation. - Enabled does not mean running: Enabled and Disabled describe the value in the agent's config file. ## Configuration files BFrost reads - Claude Code: ~/.claude.json - Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) - Cursor: ~/.cursor/mcp.json - Codex: ~/.codex/config.toml (TOML) - Gemini CLI: ~/.gemini/settings.json - OpenCode: ~/.config/opencode/opencode.json - Windsurf: ~/.codeium/windsurf/mcp_config.json - Antigravity IDE: ~/.gemini/config/mcp_config.json or .agents/mcp_config.json - VS Code: the profile mcp.json or .vscode/mcp.json, using the "servers" key Remaining agents follow their own documented paths. The app shows the exact source file for every entry it discovers. ## Pricing - BFrost Early Adopter License: $19.99 USD, one-time purchase, first 500 customers. - Standard price afterwards: $39.99 USD, one-time purchase. - Includes one year of updates and the macOS download (Apple Silicon and Intel). - Windows support is in development. - Checkout: Stripe. After payment the buyer lands on a secure download page and receives the same link by email. ## Status and roadmap - Current release line (0.1) includes discovery, guided editing, Skills management, repeated-server detection, saved servers, backups, and conflict detection. - Planned, without promised dates: license activation, opt-in anonymous diagnostics (off by default), an explicit configuration verification action, and Windows support. ## Related MIMR products - MIMR Growth Lab: https://mimrgrowthlab.com/ - GTM and growth services. - Muninn: https://muninn.mimrgrowthlab.com/ - Your agency's brain and Skills as MCP. - TapeGIF: https://tapegif.mimrgrowthlab.com/ - Turn terminal work into GIFs. ## Terms - MCP: Model Context Protocol. - MCP server: a tool server used by an AI agent. - Agent Skill: a saved instruction or capability folder (SKILL.md plus supporting files) used by an agent. - User scope: configuration for a user rather than a single project. - Project scope: configuration for one project folder. - Saved server: a local copy of a server's settings that can be copied into another agent's config file. - Linked copy: a shared Agent Skill that multiple agents reference. - View-only: an entry BFrost can discover but not safely edit. - Enabled/Disabled: the on/off value in an agent's config file, not a runtime health status.
