What does it add to Hermes?
Gsa Perdiem is a MCP server related to extending the agent. It adds a capability or workflow to Hermes. The publisher description explains the intent, while granted permissions determine what it can actually do.
This plain-language explanation is based on the publisher description. The original text remains visible for verification.
Do not add it merely to experiment when Hermes already has a simpler path, or when you cannot review its source and permissions and streamable-http transport.
Best for users who understand read versus write access and authentication.
Start with non-sensitive data and a small task whose result can be verified and reversed.
Original publisher description
GSA Per Diem MCP — wraps the GSA Per Diem API v2 (api.gsa.gov)
Data source
This entry was indexed from Official MCP Registry. Our explanation interprets the type and domain without inventing a capability not present upstream.
Security review
Inspect transport, authentication, and the tools exposed by the MCP server. Start with the smallest tool set.
Inspect, install, then test.
- 01Open the source
Match the publisher, license, and description to your need. Check the real update history.
- 02Review permissions and secrets
Never paste a secret value into this site. Use environment-variable names and grant the smallest scope.
- 03Copy setup only after review
The controls below copy text. They do not execute commands on your device.
- 04Test with a non-sensitive task
Inspect the visible tools, then exclude write or delete tools you do not need.
