Frequently asked questions
Which MCP server is faster to set up, Notion MCP or Obsidian MCP?
Notion MCP typically installs via a single npm or pip command and asks for Notion integration token. Obsidian MCP needs local vault path + plugin key. Expect 2-5 minutes for either once credentials are ready. If you already have Notion configured, Notion MCP wins by a minute or two.
Can I run Notion MCP and Obsidian MCP side by side in the same Claude client?
Yes. Claude Desktop, Cursor, and Claude Code all accept multiple MCP servers in the same config file. Each runs in its own process and exposes a distinct tool namespace, so there are no naming collisions. Memory usage is additive; budget roughly 40-80 MB per server.
How do Notion MCP and Obsidian MCP compare on cost?
Notion MCP is free server, Notion plan applies. Obsidian MCP is free, OSS. Most of the real spend is on the underlying service, not the MCP server itself; the server is almost always free. Budget based on query volume at the backend, not the MCP layer.
Is Notion MCP or Obsidian MCP more production-ready?
Notion MCP is maintained by Notion, which tends to mean faster fixes. Obsidian MCP is community-maintained too; same diligence applies. For critical workloads, pick the vendor-backed option or pin a specific version.
What authentication does each server need?
Notion MCP authenticates with Notion integration token. Obsidian MCP uses local vault path + plugin key. Store secrets in a password manager or your shell's keychain and inject them via environment variables; never commit them to the MCP config file, which is often synced across machines.
Which one should I pick first if I am just starting with MCP?
Start with whichever backend you already pay for or use daily. If you do not use either yet, Obsidian MCP is fully OSS, so there is no signup friction. You can always add the second one later without disrupting the first.
