Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable cmd/sage-gui/backup_full.go:155, cmd/sage-gui/cert_status.go:31, cmd/sage-gui/connect.go:206 и ещё 38

        archivePath = filepath.Join(backupDir, fmt.Sprintf("sage-full-%s.tar.gz", stamp))

Builds a database query by concatenation internal/store/sync_tables.go:630, internal/mcp/http_transport.go:170, web/static/js/federation-connectome.js:326 и ещё 2

        if _, err := tx.writeExecContext(ctx, `UPDATE pipeline_transport_outbox
            SET state='failed',
                attempts=attempts + CASE WHEN state='pending' THEN 1 ELSE 0 END,

Runs an external command cmd/sage-tray/main.swift:134

        let process = Process()

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Sage — questions

Answers built from our own checks of this server.

Why is there no uptime for Sage?

Sage runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.

Is Sage open source?

Yes — it is published under the Apache-2.0 licence, written in Go, 259 stars on GitHub and 4 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
