## What it does

PostLake runs as a remote MCP server at `https://api.postlake.dev/mcp`. There is no local process to start and nothing to self-host. You register the server in your MCP client and approve the PostLake OAuth flow in a browser once, after which the agent can act on the accounts you connected. Nine platform SDKs and nine auth models collapse into a single tool surface with one result shape.

The server exposes 63 tools grouped by outcome. `create_post` and `create_scheduled_calendar` handle publishing, `validate_post` runs a free dry run first, `upload_media` takes care of files, and `list_conversations` plus `reply_to_comment` cover the inbox. Idempotency keys make retries safe, and `confirm_post` checks an asynchronous provider after it accepts a post. Every call reports the result per target, so a partial failure stays visible instead of looking like success.

The account owner can require approval on an OAuth connection. When that is on, publish requests from the agent land as drafts and the agent cannot approve its own work; access is revoked from the PostLake dashboard. No social-network password is involved. Agents running on an API key instead need `POSTLAKE_API_KEY` set in their runtime, otherwise the skills have nothing to authenticate with.
