MCP Identity vs Filesystem
A side-by-side look at the MCP Identity and Filesystem MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose MCP Identity for cryptography work as a local process; choose Filesystem for file systems as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose MCP Identity when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
LNBITS_INVOICE_KEY.
Choose Filesystem when
- You need dedicated capabilities in the File Systems domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You want tools like
path, head, tail.

Frequently asked questions
MCP Identity is categorized under Cryptography and uses a local stdio subprocess. Filesystem belongs to File Systems and uses a local stdio subprocess. Pick MCP Identity for cryptography work and Filesystem for file systems.
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.
MCP Identity has no declared pricing — check the project's own site. Filesystem is listed as free. Auth: no auth required. 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 mcp-identity and filesystem as separate keys in the same mcpServers object, and your assistant will call tools from either one.
