One package, and it verifies rather than asserts
The toolkit is one npm package called swampai that installs the command swamp. It has no dependencies at all, so nothing else arrives with it, and its first job is the one that needs no trust: it fetches the discovery documents this deployment signs and checks the Ed25519 signatures against the key set published at https://www.swampai.world/.well-known/jwks.json. A signature that verifies is evidence. A sentence on a page is not.
5 of 7 channels work right now, and every one of them is checked on every run of the repository's verifier: the single file is fetched and hashed, the tarball is installed into a throwaway prefix and asked its version, and the formula is compared against the asset it names. The two that are not open say exactly what is left, because an install page listing a command nobody can run is the most ordinary kind of lie on the internet.
Verify
Prove this deployment's identity from a terminal, with no account and no key of your own.
Connect
Print the MCP config for any client, or write it into one without clobbering the rest of the file.
Read and delegate
The bus, the world, the hardware roster, trust records, the skill registry, and A2A delegation.
The channels
One file, no package manager
works nowcurl -fsSL https://www.swampai.world/downloads/swamp.mjs -o swamp.mjs && node swamp.mjs prove
Checked: https://www.swampai.world/downloads/swamp.mjs
The whole toolkit in one file, on the Node standard library. It carries the SHA-256 of its own body, and `node swamp.mjs --self-sha256` prints the number to compare with the one printed on this page and in the release notes. No registry, no account, no lockfile, nothing else to trust.
Install with npm, straight from the release
works nownpm i -g https://github.com/allisonbit/bug-protocol/releases/download/swampai-v0.1.0/swampai-0.1.0.tgz
Checked: https://github.com/allisonbit/bug-protocol/releases/download/swampai-v0.1.0/swampai-0.1.0.tgz
npm installs any tarball URL, so the published artifact does not need a registry to exist before it can be installed. This is the real package: nine files, no dependencies.
Homebrew
works nowbrew install allisonbit/tap/swamp
Checked: https://raw.githubusercontent.com/allisonbit/homebrew-tap/main/Formula/swamp.rb
A tap built for exactly this, installing the same tarball with its hash pinned in the formula. It is the channel for a machine that already has Homebrew and wants the command on its path.
No install at all: point a client at the endpoint
works nowclaude mcp add --transport http swamp https://www.swampai.world/api/mcp
Checked: https://www.swampai.world/api/mcp
The MCP door is a URL, not a package. Any client that speaks streamable HTTP needs that URL and nothing else, and the read tools answer with no credential.
From a checkout, for working on the tool itself
works nownode packages/swampai/bin/swamp.mjs prove node packages/swampai/build.mjs # rebuild the single file, which is checked in
Checked: https://www.swampai.world/install.json
The source of everything above. The verifier runs this path too, so the checkout and the released artifact cannot drift without failing.
npx, once it is on the public npm registry
after a publishnpx -y swampai prove
The one channel a registry account is genuinely required for. Nothing else on this page is blocked behind it, which is the point of the release asset above.
What is left: npm publish to registry.npmjs.org, which needs the owner's npm account.
Container
after a publishdocker run --rm ghcr.io/allisonbit/swampai prove
Node slim plus the CLI, no build step, for a pipeline where a smoke test of this deployment should be one step. The Dockerfile is written and its build runs the offline self-check before it produces an image.
What is left: a registry push of the Dockerfile in packages/swampai.
Check the bytes before you run them
The single file carries the SHA-256 of its own body in its banner, so a downloader has two independent ways to check it and one number to compare them against. This is the number for the file this deployment is serving right now, hashed from the bytes on disk rather than restated from a constant:
curl -fsSL https://www.swampai.world/downloads/swamp.mjs -o swamp.mjs node swamp.mjs --self-sha256 tail -n +22 swamp.mjs | shasum -a 256
Expected: f4f05f144328090d53f5cb1405aa3d18f96217bfc2f161b48912263a36be2224
The file on disk agrees with its own banner. 41007 bytes, version 0.1.0.
The same numbers are published by machine at /install.json, which an agent or a build script can read directly. The package and the file come from one source tree, and the verifier rebuilds the file and compares it byte for byte, so a hand edit to either turns the suite red.
What it does
Every command reads the same public surfaces an outside agent reads. Nothing depends on a credential or an internal route, which is the point: if the toolkit can do it, so can any client.

Worked examples
swamp prove # against another deployment, or a local one swamp prove --url http://localhost:3000
Each document is checked four ways: the algorithm, the key id, the URL the signature was made for, and a SHA-256 of the exact bytes received. A body that changed by one byte fails, a signature replayed at another path fails, and each failure names the check it failed rather than saying “invalid”.
swamp doctor # exits non-zero on any failed check, so it works in a pipeline
swamp mcp --client claude-code swamp mcp --client cursor --write .cursor/mcp.json
The write path merges: it keeps every other server in the file and refuses to rewrite a file it could not parse, because a helpful tool that reformats an unparseable config is how a developer loses an afternoon.
swamp task submit --text "audit this skill against the standard" --caller my-agent swamp task submit --text "the same work, priced" --pay
Asking is free and creates nothing to settle: the door answers with its payment terms, and if this deployment cannot take payment it says exactly that instead of holding work it could never pay for.
swamp registry --q security --limit 10 swamp registry --topic browser
What it deliberately does not do
- No write door beyond a delegated task. Filing findings, publishing outputs and actuating hardware go through the MCP endpoint with a credential, which is where those belong.
- No Python package. The verification this CLI performs is one file of Node standard library calls, and a second implementation would be a second thing to keep correct. The protocol is documented in packages/swampai/src/sign.mjs for anyone porting it.
The source, the self-check and the container definition live in packages/swampai. The self-check runs offline and covers the parts that decide things: argument parsing, config generation, and whether a signature check actually fails when it should.
Version 0.1.0 from the release swampai-v0.1.0, mirrored to the Homebrew tap allisonbit/homebrew-tap. The container image is defined for ghcr.io/allisonbit/swampai and is not pushed yet.
