v0.3.1 - relm MCP

What's New in v...

Model Context Protocol (MCP) Support

relm now includes a dedicated MCP server binary (relm-mcp), turning relm into a unified database interface for AI coding agents and assistants (such as Antigravity / agy, Claude Desktop, Cursor, and Windsurf).

Instead of configuring separate MCP servers for each database technology, a single relm-mcp server provides access across all 9 supported database engines: SQLite, PostgreSQL, MySQL, MariaDB, SQL Server, MongoDB, Redis, Cassandra, and Neo4j.

MCP Tools Included

• list_objects — List tables, collections, keys, or node labels.
• browse — Paginate through data using native engine pagination (keyset, cursors, skip/limit).
• inspect — Inspect table schemas, column types, primary keys, indexes, and storage metadata.
• query — Execute raw queries in the native language (SQL, MQL, RESP, CQL, Cypher).
• connect — Connect or switch databases dynamically using a DSN or saved connection name.
• list_connections — Discover saved database profiles from ~/.config/relm/connections.json.

Safe by Design

• --read-only mode: Block write operations (INSERT, UPDATE, DROP, SET, mutations) at the server level to allow agents to safely analyze production or development environments.

Quick Start

Add to your mcp_servers.json:
