Aletheia MCP Server

local only

Aletheia runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 24 Oct 2026.

Project memory for coding agents whose memories carry code evidence, re-checked on every recall.

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.

const child = spawn(bin, process.argv.slice(2), { stdio: "inherit", windowsHide: true });
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Builds a file path from a variable cmd/aletheia/capture.go:165, internal/store/store.go:82
        p = filepath.Join(root, p)

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.

Aletheia — questions

Answers built from our own checks of this server.

Why is there no uptime for Aletheia?
Aletheia runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @firatmio/aletheia.
How do I connect Aletheia?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @firatmio/aletheia straight from npm; nothing to host, nothing to sign up for.
Is Aletheia open source?
Yes — it is published under the Apache-2.0 licence, written in Go, 8 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
