EctoClaw — Cryptographic Audit Ledger & AI Firewall for OpenClaw

Configuration

• - ECTOCLAW_URL: The EctoClaw server URL (default: http://localhost:3210)

Source code and install scripts are fully open-source at https://github.com/EctoSpace/EctoClaw.

Security / authentication

• - EctoClaw is designed to run on localhost or a private network you control.
• If you expose ECTOCLAWURL beyond localhost, put it behind your own authentication and access controls (for example, a reverse proxy with auth).
• Do not point ECTOCLAWURL at an untrusted third-party host, since audit logs can contain sensitive prompts, tool outputs, and memory contents.

Commands

List Audit Sessions

When the user asks to see audit sessions, list recent sessions, or check audit history:

• - Call GET {ECTOCLAW_URL}/api/sessions?limit=10
• Format the response as a readable list showing session ID, status, event count, and goal

Create Audit Session

When the user asks to start a new audit, create a session, or begin tracking:

• - Call POST {ECTOCLAWURL}/api/sessions with JSON body: {"goal": ""}
• Optionally include "policyname" to bind a policy: {"goal": "", "policy_name": ""}
• Report the session ID, goal hash, and public key

Append Event

When the user wants to log an action, record an event, or track an operation:

• - Call POST {ECTOCLAWURL}/api/sessions/{sessionid}/events
• JSON body: {"type": "", "payload": {}}
• Valid types: MessageReceived, MessageSent, SkillInvoked, SkillResult, ToolCall, ToolResult, PluginAction, PluginResult, ModelRequest, ModelResponse, MemoryStore, MemoryRecall, ApprovalRequired, ApprovalDecision
• Report the content hash, sequence number, and Ed25519 signature

Verify Session Integrity

When the user asks to verify a session or check chain integrity:

• - Call GET {ECTOCLAWURL}/api/sessions/{sessionid}/verify
• Report whether the hash chain is verified or broken and how many events were checked

Get Session Details

When the user asks about a specific session:

• - Call GET {ECTOCLAWURL}/api/sessions/{sessionid}
• Show full session details including goal, goal hash, status, policy, timestamps, event count, and public key

Seal a Session

When the user asks to finalize, seal, or close an audit session:

• - Call POST {ECTOCLAWURL}/api/sessions/{sessionid}/seal
• Report the sealed status and final Merkle root

Get Audit Metrics

When the user asks for metrics, statistics, or a summary:

• - Call GET {ECTOCLAW_URL}/api/metrics
• Display total sessions, active sessions, sealed sessions, total events, and event type breakdown

Get Compliance Bundle

When the user asks for a compliance report or Merkle proof:

• - Call GET {ECTOCLAWURL}/api/sessions/{sessionid}/compliance
• Show the Merkle root and event hashes

Get Merkle Proof for Specific Event

When the user asks to prove a specific event exists in the chain:

• - Call GET {ECTOCLAWURL}/api/sessions/{sessionid}/merkle?leaf={event_index}
• Show the Merkle root and inclusion proof path

Verify a Merkle Proof

When the user provides a Merkle proof to verify:

• - Call POST {ECTOCLAW_URL}/api/merkle/verify with the proof data
• Report whether the proof is valid

Generate Audit Report

When the user asks for a full audit report:

• - Call GET {ECTOCLAWURL}/api/reports/{sessionid}?format=json
• For HTML: GET {ECTOCLAWURL}/api/reports/{sessionid}?format=html
• Present the complete session report with events and verification status

List Policies

When the user asks about active policies or what rules are configured:

• - Call GET {ECTOCLAW_URL}/api/policies
• Show each policy name and its configuration

Create or Update a Policy

When the user wants to set up audit rules:

• - Call PUT {ECTOCLAW_URL}/api/policies/{name} with {"content": ""}
• Report the saved status

Stream Live Events

When the user wants real-time monitoring:

• - Connect to GET {ECTOCLAW_URL}/api/stream (Server-Sent Events)
• Report events as they arrive

Check Server Health

When the user asks if EctoClaw is running:

• - Call GET {ECTOCLAW_URL}/health
• Report status, version, and name

What EctoClaw records

Every OpenClaw lifecycle event is captured as a signed ledger entry:

Event Type	What it captures
MessageReceived	Inbound messages from any channel
MessageSent

Outbound agent responses |
| SkillInvoked | Skill activation with parameters |
| SkillResult | Skill execution output |
| ToolCall | Tool invocations (shell, file, http, browser) |
| ToolResult | Tool execution results and observations |
| PluginAction | Plugin lifecycle events |
| ModelRequest | LLM API calls with prompt context |
| ModelResponse | LLM responses |
| MemoryStore | Memory write operations |
| MemoryRecall | Memory read operations |
| PolicyViolation | Blocked or flagged actions |
| ApprovalRequired | Human-in-the-loop gate triggered |
| ApprovalDecision | Human approval or denial recorded |
| SessionSeal | Session finalized with Merkle root |
| KeyRotation | Ed25519 signing key rotated |

Only send data to an EctoClaw instance you operate and trust. Treat audit logs as highly sensitive and protect them accordingly.

Cryptographic integrity

Every event is:

1. 1. SHA-256 hash-chained — each event hash includes the previous event hash
2. Ed25519 signed — tamper-evident digital signatures per event and per session
3. Merkle tree provable — O(log n) inclusion proofs for any individual event

Quick start (for users installing EctoClaw)
