mcs-types-cache 0.1.0

Shared cache types (CachePort, FileCacheStore) for the Model Context Standard.

mcs-types-cache

Shared cache types for the Model Context Standard (MCS).

Contains CachePort (the protocol any cache backend must satisfy) and FileCacheStore (the default file-based implementation).

This package has zero dependencies. It exists so that credential providers, drivers, and other MCS components can persist state across process invocations without coupling to a specific storage backend.

Installation

pip install mcs-types-cache

Most users don't need to install this directly -- it's pulled in automatically by mcs-auth and other packages that use caching.

Usage

from mcs.types.cache import CachePort, FileCacheStore

# File-based cache (default)
cache = FileCacheStore(".mcs_token_cache")
cache.write("my_key", "my_value")
assert cache.read("my_key") == "my_value"
cache.delete("my_key")
assert cache.read("my_key") is None

Custom backends implement CachePort:

class RedisCacheStore:
    def read(self, key: str) -> str | None: ...
    def write(self, key: str, value: str) -> None: ...
    def delete(self, key: str) -> None: ...
