"Facebook" matching MCP servers:

A Facebook/Messenger MCP server that lets AI agents read and engage with profiles, pages, posts, comments, groups, Messenger conversations, notifications, and events using the user's existing browser session cookies — no Graph API app, tokens, or browser automation required. It supports multi-account and Page switching, write operations (posting, commenting, messaging) with per-identity limits and cooldowns, and honest error reporting where Meta has decommissioned cookie-era endpoints.

Enables Claude to monitor Facebook Marketplace car and motorcycle listings, score them against custom criteria, and analyze accumulated listing history to reveal time-on-market, price trends, and sale triggers.
