Common questions
Is Fathom safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, zanadir

Current release: 1.0.0 (2026-10-29). Deferred items are listed in COMPLIANCE.md; release history in CHANGELOG.md.
Clean-room reverse-engineering MCP, written in Rust: one provider-neutral MCP server for reverse engineering — native binaries, JavaScript/Electron applications, .NET assemblies, web captures, EVM bytecode, and process behavior — where every result is an evidence envelope that states what was observed, what was derived, what was not examined, and what the provider cannot establish.
The design is specified in SPEC.md: capability inventory mapped from upstream's public contracts, per-capability Rust strategy, evidence and error models, a deterministic fail-closed policy engine, and the staging plan. Design source: morluto/rea (MIT), credited in NOTICE; no upstream code is used.
Why clean-room Rust
Upstream REA is TypeScript/Node distributed through npm. Fathom exists to keep the capability on a Rust-first, pinned, auditable supply chain — the estate's standing direction (SPEC §1).
