What LINQ to DB does

According to its repository: “Inspect database schemas and execute SQL queries across multiple database providers with LINQ to DB.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. LINQ to DB is listed under Databases, a category of 138 servers in the directory, where it ranks #6 by stars.

Topics declared by the repository: linq, database, orm, sql, access, db2.

Installing and connecting LINQ to DB

Distribution modes declared in the official MCP registry:

  • NuGet package (.NET)

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: C#.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to LINQ to DB. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on June 18, 2011, the linq2db/linq2db repository has 3,335 stars and 482 forks, with 433 open issues. It has more stars than 96% of the servers in the directory. It received changes this month. Version published in the registry: 6.5.1 (October 23, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
