pgmoneta MCP

pgmoneta MCP is the official Model Context Protocol server built for pgmoneta, a backup / restore solution for PostgreSQL.

Overview

pgmoneta MCP is built upon rmcp.

It uses SCRAM-SHA-256 to authenticate with pgmoneta server.

User management is done with the administration tool called pgmoneta-mcp-admin. Interactive tool execution is available through pgmoneta-mcp-client, while pgmoneta-mcp-inspector provides a more structured inspection CLI.

OpenAI API support

The native pgmoneta MCP client communicates with language models through the OpenAI API. For a local model, the documented server is orangu-server.

Start an installed model:

orangu-server --all ggml-org/gemma-4-E4B-it-GGUF

Point pgmoneta-mcp-client at its OpenAI endpoint:

[pgmoneta_mcp_client]
url = http://localhost:6432/mcp
timeout = 30
model = gemma

[gemma]
provider = openai
endpoint = http://localhost:8100/v1
model = ggml-org/gemma-4-E4B-it-GGUF
max_tool_rounds = 10

See doc/LOCAL_LLM.md for the setup.
