Filesystem vs Mychart
A side-by-side look at the Filesystem and Mychart MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Filesystem for file systems work as a local process; choose Mychart for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.

Frequently asked questions
Filesystem is categorized under File Systems and uses a local stdio subprocess. Mychart belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick Filesystem for file systems work and Mychart for biology & bioinformatics.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Filesystem is listed as free. Auth: no auth required. Mychart has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add filesystem and mychart as separate keys in the same mcpServers object, and your assistant will call tools from either one.
