Quick answers
Is Postman MCP Server better than Microsoft 365 MCP Server?
Package installs favor Microsoft 365 MCP Server: 177,818 monthly installs to 35,148. Postman MCP Server still ranks #4 of 250 maintained API integration servers. Data as of 2026-08-25; we haven't hands-on tested either.
Can I use Postman MCP Server and Microsoft 365 MCP Server together?
Yes - MCP clients accept multiple servers in one config, so you can enable both API integration servers side by side. If their tools overlap, keep the one whose toolset fits to keep your agent's tool list lean.
What environment variables do their READMEs document?
Postman MCP Server: no environment variables extracted from the README setup; Microsoft 365 MCP Server: 12 environment variables extracted from the README setup. Extraction does not rule out other authentication or configuration steps; check each project's current documentation.
