Frequently asked questions

Filesystem is categorized under File Systems and uses a local stdio subprocess. Pubcrawl belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick Filesystem for file systems work and Pubcrawl 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. Pubcrawl 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 filesystem and pubcrawl as separate keys in the same mcpServers object, and your assistant will call tools from either one.
