What is KyttoMCP?

Editorial review
KyttoMCP is a local control panel for Model Context Protocol servers. It is not itself a server an agent calls but the layer above them: one interface that reads the MCP configuration files used by Claude Desktop, Claude Code, Cursor, VS Code, and Codex, shows what each client has enabled, and edits those configs in place. That addresses the problem anyone running more than a handful of servers runs into, where the same entry has to be copied, tweaked, and kept in sync across several JSON files by hand. Beyond editing, it inspects. Running a handshake against a configured server returns its advertised tools, prompts, and resources along with protocol details and stderr output, which is how a silently failing server gets diagnosed instead of guessed at. It estimates the context window cost of each server and of a whole configuration, flags duplicate tool names across servers, and warns when a stack is over budget. Profiles group servers into focused sets, so a coding stack and a research stack can be swapped without retyping anything. Every change is preceded by a timestamped backup with atomic writes and external change detection, and earlier configurations can be browsed and restored. It targets developers who have accumulated enough MCP servers that configuration became its own maintenance task. Everything runs locally with no account and no cloud sync, credentials stay on the machine with optional masking and system keychain storage, and activity logging records metadata without capturing payloads.

KyttoMCP FAQ

How does KyttoMCP help a developer who uses both Claude Desktop and Cursor for AI coding?

KyttoMCP provides a single local control panel that manages MCP servers across both Claude Desktop and Cursor, along with Claude Code, VS Code, and Codex. It reads the local JSON and TOML configuration files for each tool, shows health and protocol details, and lets you switch between profiles without editing files manually.

How does KyttoMCP compare to DevToys?

KyttoMCP is purpose-built for managing MCP servers across AI coding tools like Claude and Cursor, while DevToys is a general-purpose developer utility. KyttoMCP offers features like profiles, secret management, timestamped backups, and atomic writes specifically for MCP server configurations, which DevToys does not provide.

Can KyttoMCP manage MCP servers outside of the listed applications, or is it limited to those?

KyttoMCP is designed to work with Claude Desktop, Claude Code, Cursor, VS Code, and Codex. It reads local JSON and TOML configuration files from those specific tools, so it does not manage MCP servers for other applications or environments.

Which teams would benefit most from using KyttoMCP?

Teams that use AI coding assistants like Claude and Cursor and need to centrally manage MCP server configurations across multiple developers’ local machines will benefit most. KyttoMCP simplifies maintaining consistent profiles, secrets, and backups without requiring manual file editing.

How is KyttoMCP priced?

KyttoMCP is free to use with no paid plan required. There are no subscription fees or hidden costs for accessing any of its features.

Does KyttoMCP provide any backup or versioning for configuration changes?

Yes, KyttoMCP creates timestamped backups of your MCP server configurations and uses atomic writes to prevent data corruption. This ensures you can restore previous configurations if needed.

How does KyttoMCP read and manage configuration files?

KyttoMCP reads local JSON and TOML configuration files from the supported tools and displays their health and protocol details. It then allows you to modify those configurations through profiles, secret management, and backups, writing changes atomically to preserve file integrity.

What kind of secret management does KyttoMCP offer?

KyttoMCP includes built-in secret management that lets you store and reference sensitive values like API keys within your MCP server configurations. These secrets are handled locally, keeping them off remote servers and within your control.
