Frequently Asked Questions
Everything you need to know about MCP & Clardan
What is the Model Context Protocol (MCP)?
Model Context Protocol (MCP) is an open standard developed by Anthropic that enables AI assistants like Claude to securely connect to external data sources, enterprise tools, and local APIs. It standardizes how AI models discover tools, pass structured JSON-RPC parameters, and handle execution responses.
How does Clardan Studio integrate with Claude Desktop?
Clardan compiles your visual tool schemas directly into standardized configuration objects. With our 1-click sync, you can directly register your local MCP servers into claude_desktop_config.json without manual file edits or syntax errors.
What languages can I export from Clardan Studio?
Clardan outputs battle-tested, idiomatic code for both official SDK ecosystems: TypeScript using Anthropic's @modelcontextprotocol/sdk and Python using FastMCP. We also support pure JSON Schema 7 exports.
What clients support tools built with Clardan?
Any client compliant with MCP can consume your tools. This includes Claude Desktop, Cursor AI, Claude Code CLI, Sourcegraph Cody, Zed Editor, and custom autonomous multi-agent pipelines built with LangGraph or CrewAI.
Is Clardan free for developers?
Yes. The visual schema builder, local Claude simulator, and unlimited TypeScript and Python SDK exports are completely free on our Community plan for individual builders.
