Sifter: MCP server, setup and security

Sifter is an open-source MCP server published on GitHub that lets an AI agent extract structured records from documents and query them using natural language. Its repository has 54 stars and its last commit is from September 17, 2026 and it is licensed under MIT.

Actively maintained

What Sifter does

According to its repository: “Extract typed, schema-defined records from any document and query them in natural language like a database.”

The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Sifter is listed under Web search and extraction, a category of 159 servers in the directory, where it ranks #65 by stars.

Installing and connecting Sifter

No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.

It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: Python.

Security: what to check

Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Sifter. 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 April 17, 2026, the sifter-ai/sifter repository has 54 stars and 1 forks, with 0 open issues. It has more stars than 53% of the servers in the directory. Last change 1 month ago.

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