打开 Claude Desktop → Settings → Developer → Edit Config，把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "altweb-context": {
      "command": "npx",
      "args": [
        "-y",
        "altweb-context"
      ],
      "env": {
        "ALTWEB_TRUST_FILE": "your-value"
      }
    }
  }
}

在终端中运行这条命令

claude mcp add altweb-context --env ALTWEB_TRUST_FILE=your-value -- npx -y altweb-context

运行前请先填写空着的值。

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json，或 ~/.cursor/mcp.json

{
  "mcpServers": {
    "altweb-context": {
      "command": "npx",
      "args": [

需要你填写的值

ALTWEB_TRUST_FILE env
Override the local trust file of allowed signer public keys (default: ~/.altweb/trusted-keys.json). A missing or empty trust file refuses every capsule.

ALTWEB — signed context capsules

Signed context capsules for AI agents — Markdown compiled into self-contained, verifiable, optionally encrypted artifacts + an MCP loader that refuses unsigned or untrusted context. Verify before you inject.

AI agents run on plain-text context: instructions, personas, skills, memory files. None of it has provenance — anything that can write those files can poison them. ALTWEB gives context a chain of custody, and makes the loader refuse anything that lacks one:

Capsule — markdown compiled into a single .altweb.html file (or URL): content compressed (deflate), optionally encrypted (AES-256-GCM), optionally signed (ECDSA P-256). Self-contained — opens in any browser, verifies offline, needs no server: you hand someone a file, not a database.
Verified context loading — the altweb-context MCP server loads a capsule into your agent *only* when the signature is valid and the signer's public key is in your trust file. Unsigned, tampered, or untrusted capsules are refused at load time, with an explicit reason. Refusal is the default: an empty trust file rejects everything, signed or not.

you write MD ──► altweb compile --sign ──► capsule (.altweb.html / URL)

│ agent asks for context ──► altweb-context ──► verify signature + trust │ trusted ──► markdown injected everything else ──► REFUSED (reason)

Packages

Package	What it is
`altweb`	CLI: `altweb compile / decode / verify / keygen` (`packages/cli`)
`altweb-context`	MCP server: `load_capsule`, `verify_capsule`, `list_trusted_keys` (`packages/mcp`)
`@altweb/core`	Headless engine: content model, codec, crypto, markdown, sanitize (bundled into both; npm release planned)
`@altweb/editor`	Notion-style editor (built on Novel) with one-click capsule export
`site/`	Documentation site (Astro + Starlight)

Quickstart

Both tools are on npm — nothing to clone. Run these commands outside a source checkout (inside this repository, npm resolves the local workspace package):

# create your signing identity (deterministic from a passphrase; only the

public key + fingerprint are stored, in ~/.altweb/identity.json)

npx altweb keygen --save

write, compile, sign

echo "# My agent's operating notes" > notes.md npx altweb compile notes.md -o notes.altweb.html --sign

verify anywhere, offline

npx altweb verify notes.altweb.html

Wire the loader into an MCP client (Claude Code example):

claude mcp add altweb-context -- npx -y altweb-context

(From source: npm install && npm run build, then use the bundles under packages/*/dist/.)

Running from source

Node.js 20 or newer is required. From the repository root:

npm install

npm run build

Create and save an identity with the locally built CLI

npm run keygen

Start the editor in development mode

npm run dev

The editor prints its local URL (normally http://localhost:5173). The CLI can be invoked as node packages/cli/dist/altweb.mjs . Do not use npx altweb inside the checkout: npm may select the local workspace package, whose executable does not exist until it has been built.

The documentation site is intentionally a separate npm project rather than a workspace. To run it locally:

npm install --prefix site

npm run dev --prefix site

Trust a signer by adding its full public key to ~/.altweb/trusted-keys.json (the UNTRUSTED_KEY refusal message hands you the ready-made entry; the short fingerprint is a human label, not the trust anchor):

{ "keys": [ { "name": "Me", "publicKey": "<base64url SPKI>", "fingerprint": "ab:12:..." } ] }

What a signature proves — and what it does not

A valid signature proves who authored the capsule and that the bytes are intact. It does not make the content safe or true. The trust file is your policy; keep it short.

Pick a long passphrase. Identities derive deterministically from your passphrase via Argon2id with a fixed protocol salt (that is what makes them portable with nothing stored). Memory-hardness makes mass dictionary attacks economically hostile, but the passphrase's entropy is still the identity's foundation. Use a 16+ character diceware-style phrase; the tooling enforces a minimum strength.

Security

Content is sanitized with DOMPurify on decode; artifacts carry a CSP; the codec validates structure with zod. See site/ docs → Security model for the full write-up, including the encrypted-capsule caveat (the signature covers the decrypted payload, so verification completes after decryption).

Roadmap

Near-term, in rough order:

`@altweb/core` on npm — the engine as an installable library, for programmatic use (the CLI and loader already ship it bundled).
Hardware-backed identity (FIDO2 / passkeys) — an *optional* identity type alongside the passphrase one: the private key lives in a security key or secure enclave, never extractable, signing requires physical presence. The passphrase identity stays the default — "a passphrase is a keypair" — hardware keys add *something you have* for those who want it.
