monark

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed external MCP integration for prediction gating, with no hidden local code or persistence found.

Before installing, treat the MONARK endpoint as a third-party public service: send only the prediction fields and calibration scores needed for the gate, avoid secrets or personal data, and use the documented include/exclude controls if you only need selected tools.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Transmission

Data Exfiltration
Confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Endpoint: `https://mcp.monarkgate.tech/mcp` (HTTP/JSON mirror: `POST https://api.monarkgate.tech/{attest|gate|cascade|calibrate}`). Every call is
stateless — MONARK stores nothing between the two calls; you carry q̂ and B_t in and out. The request
bodies below are shown against the HTTP/JSON mirror (`POST /{tool}`); over MCP the SAME body travels as
the `arguments` of a `tools/call`, which is the form the recorded trace captures.

Confidence
92% confidence
Finding

The document instructs agents/operators to connect to a public unauthenticated external MCP/HTTP endpoint, which creates an explicit data egress path to third-party infrastructure. In the context of an agent skill, this is security-relevant because prompts, tool inputs, predictions, scores, or workflow metadata sent to the endpoint could disclose sensitive information and create dependency on an untrusted remote service.

MONARK is one public MCP endpoint exposing the four tools `{attest, gate, cascade, calibrate}`:

- `https://mcp.monarkgate.tech/mcp` (HTTP/JSON mirror: `POST https://api.monarkgate.tech/{attest|gate|cascade|calibrate}`)

Transport is Streamable HTTP. The endpoint is public and unauthenticated, with no availability
commitment; treat it as a reference implementation of the coverage-gate contract, not a hosted service

Skill Enumeration

Medium
Category
Agent Snooping
Confidence
80% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

## Discovery

The governed source of this skill is `skills/monark/SKILL.md` in the MONARK repository.
`.agents/skills/monark/SKILL.md` is a **consumer-side, post-install** path: an operator obtains it by
installing from ClawHub (per ClawHub's own install instructions) or by copying the source directly.
MONARK does **not** generate `.agents/skills/` in its own repository. In-repo discovery is **OpenClaw-only** (its workspace `skills/` tier is open by default);

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
