FAQ
Filesystem vs Memory: which MCP server should I use?
Pick Filesystem when reading and editing local code. Pick Memory when long-running agent workflows. Filesystem is built for read & write local files, while Memory focuses on persist knowledge graph.
Can I run both Filesystem and Memory together?
Yes. MCP clients run each server as a separate process and surface every server's tools simultaneously, so you can install both and let your agent decide which to call. Be deliberate with auth scopes when stacking servers.
