metaharness
ruvnet
A factory that scaffolds your own branded agent harness with CLI, MCP server and signed releases.
What is metaharness?
A meta-tool that generates a custom agent "harness" from a GitHub repo: a branded npm package with its own npx CLI, MCP server, memory store, learning loop and cryptographically signed releases. It targets hosts like Claude Code, Codex and Hermes. The pitch is scaffolding a full agent toolchain in under a minute; that speed is a project claim, not measured here.
Pros & Cons
Pros
- Generates a complete, publishable agent toolchain (CLI + MCP + memory), not just a template
- Host-agnostic across Claude Code, Codex, Hermes and others
- MIT-licensed with ~876 commits and active releases
Cons
- From ruvnet, whose projects lean on generated scaffolding and bold README claims: inspect what it actually produces
- The '60-second scaffold' and the learning/witness features are unverified project claims
- You inherit a fairly opinionated stack (npm, MCP, witness-signing) whether you want all of it or not

When it is interesting
You want to spin up a branded, distributable agent CLI+MCP package without wiring the plumbing yourself.
When it is too early
You want a minimal, hand-rolled harness, or need to verify the generated code's quality before trusting it.
