"PostgreSQL" matching MCP servers:

Provides AI agents with unified access to Gmail for email management (send, read, list, labels) and PostgreSQL databases for executing queries and schema inspection.

Automata MCP safely gives Claude (or Codex or any AI Agent) fine-grained access to your WhatsApp, Telegram and PostgreSQL Claude can then read, search and summarise your conversations, query your data, and — only if you allow it — send messages and write rows.

Provides AI agents with shared communication and persistent state over HTTP and MCP, letting an agent save its progress, search and reuse other agents' prior work, coordinate tasks in shared spaces, exchange direct messages, and hand its role to a successor when a session ends. State is kept on PostgreSQL with signed, append-only records that anyone can verify.

Enables conversational expense tracking via Telegram, allowing natural language registration, querying, and summarization of expenses, with persistence in PostgreSQL and support for multiple LLM providers.

Enables AI agents to search and act on Telegram conversations, groups, channels, files, and links, with semantic search, AI-powered knowledge extraction, human-in-the-loop approvals, and PostgreSQL/pgvector persistence.

Enables Discord integration through MCP, allowing server management, messaging, channel/role management, and automatic issue capture to PostgreSQL.
