AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

msrest provides the Python client runtime for AutoRest-generated Azure SDK clients, handling serialization, deserialization, authentication, and HTTP request/response management for REST APIs.

Installation is low-friction with five runtime dependencies (azure-core, certifi, isodate, requests-oauthlib, requests), all standard libraries. However, the package is abandoned—last release was June 2022 (1522 days ago) and the repository is archived, meaning no maintenance or security updates are forthcoming.

Licensed under MIT (permissive), allowing broad use, modification, and distribution with minimal restrictions.

Usage

pip install msrest

from msrest.serialization import Serializer, Deserializer
from msrest.authentication import BasicAuthentication

serializer = Serializer()
deserializer = Deserializer()
auth = BasicAuthentication('username', 'password')

Requires Python 3.6 or later; intended for use with AutoRest-generated SDK clients, not as a standalone HTTP library.

Verdict: msrest is a stable, permissively licensed runtime for Azure AutoRest clients with low install friction, but it is abandoned as of June 2022 with no active maintenance. Suitable only for existing projects already locked to this dependency; new projects should evaluate whether azure-core or other maintained alternatives better serve their needs.

Needs verification

Whether azure-core (now a direct dependency as of v0.7.0) is the recommended migration path for new Azure SDK work
Whether the archived repository status reflects a planned transition to azure-core or a genuine end-of-life
