MCP Config Converter
Convert MCP client configurations between verified host formats with explicit loss warnings.
SOURCE CONFIGURATION
CONVERTED CONFIGURATION
Choose source and target formats, then convert locally.
Place in .vscode/mcp.json · Format verified: 2026-10-09 · Format reference
Local text inspection only. Commands, paths, URLs and annotations are untrusted data. Nothing is executed, connected, authenticated or saved.
Enable JavaScript to process locally. No server submission is available.
Move configuration between hosts deliberately.
Choose the source and target host. Servers are parsed into a normalized representation, then adapted to the target format. Commands, arguments and supported environment/header values are preserved. Original input remains unchanged.
Review every conversion warning. Host-specific settings such as sandbox policies and interactive inputs can lack equivalents. Unsupported fields are omitted with explicit paths, and unresolved interpolation stays literal with a warning. A generated portable tool filter may enable all advertised tools; narrow it before using the file.
Boundaries and formats.
Which host profiles are supported?
Cursor uses .cursor/mcp.json. VS Code uses .vscode/mcp.json with a servers root. Portable MCP here means the documented Copilot CLI / Agent Host .mcp.json subset, not a universal configuration standard. Source links and verification dates appear with host selection. Dedicated Claude Desktop validation is deferred.
What stays local?
Inputs, outputs and findings stay in browser memory. Reset and leaving the page clear workspace content. Explicit clipboard and download actions create copies under your control. Ordinary page assets still load from this site.
What are the limits?
Strict JSON only: no comments, trailing commas, duplicate keys or silently rounded numbers. Inputs are capped at 32 KiB UTF-8, 32 nesting levels and 4,000 values. Configurations permit 32 servers, 128 arguments and 64 environment/header entries per server. Conversion output is capped at 128 KiB. No remote MCP inspection is performed.
