Privacy-first unofficial Polar AccessLink v4 MCP server for AI health, sleep and training agents.

Trust verdict · v1 advisory · method

NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

Environment variables

POLAR_CLIENT_ID

Polar OAuth client ID. Optional when configured with polar-mcp-server setup.

Polar OAuth client secret. Prefer polar-mcp-server setup so this secret is stored in ~/.polar-mcp/config.json instead of MCP client config.

Redirect URI configured in the Polar AccessLink admin. Optional when configured with polar-mcp-server setup.

POLAR_TOKEN_PATH

Optional local path for OAuth tokens. Defaults to ~/.polar-mcp/tokens.json.

POLAR_PRIVACY_MODE

Optional payload mode: summary, structured, or raw. Defaults to structured. raw means full Polar AccessLink payloads for supported endpoints.

POLAR_CACHE

Optional SQLite cache toggle. Set to true or sqlite to enable.

POLAR_CACHE_PATH

Optional local SQLite cache path. Defaults to ~/.polar-mcp/cache.sqlite.

POLAR_NO_CACHE
