Five to ten AI agents on every laptop, each with multiple extension surfaces. Zero visibility for the security team.

The threats we catch

How AI agent attacks actually unfold

One attack, in detail. Dozens more in the catalog.

A contract-analyzer skill installed 6 weeks ago. 1,300 GitHub stars, active maintainer, looked legitimate. It worked. Claude summarized contracts on every analyst’s Mac. It also quietly read ~/.aws/credentials and sent them through the OCR API. Repello caught the manifest deviation, blocked the install fleet-wide, and added the pattern to the threat corpus so every other Repello customer was protected within minutes.

Claude is secure. Cursor is secure. Cowork is secure. Your laptop is the gap.

This is one attack. Repello catches these too:

CRITICAL

Prompt injection via invisible Unicode

Zero-width and directional-override characters hide instructions inside a normal-looking rules file. The agent obeys them. You can't see them.

Caught by: Unicode scan + judge

CRITICAL

Shell access via misnamed MCP server

An MCP server points its entrypoint at /bin/bash, /bin/sh, or python -c. The agent connected to it now has a shell on the laptop.

Caught by: Entrypoint inspection

HIGH

MCP server phones a domain you've never approved

Outbound calls to a domain that isn't on your vendor list. Novel, suspicious, or already on a threat feed.

Caught by: Destination check + threat feed

HIGH

Risky config spreading across projects

A developer copies an mcp.json from one repo to another. The risky config now lives in five places. The original warning didn't travel with it.

Caught by: Config drift detection

What you see

Every artefact, every endpoint, every destination.

Artefact

What it is

Examples

MCP servers

Long-running tools agents call

github-mcp · filesystem-mcp · slack-summarizer

Skills

Bundled code agents load

Claude skills · ChatGPT custom GPTs

Rules files

Persistent agent instructions

Cursor .mdc files · Claude rules

Plugins

IDE-level extensions

Copilot extensions · Cline addons

Custom hooks

User-installed agent hooks

Pre/post-tool-use scripts

Repello inventories each one, scores it, and tracks how it changes over time.

The gap nobody else sees

Every MCP server reaches an external destination.
Repello knows where.

Most AI security tools stop at “this skill exists.” Repello goes further: we map every outbound destination every MCP server in your fleet calls: verified vendors, local services, and unknown parties. The CISO sees, at a glance, where data is flowing.

Your existing tools see binaries and packets. We see that filesystem-mcp made an outbound call to gist.githubusercontent.com, and ask why.

The method

How we catch what static analysis misses.

Static caught 33% of malicious skills. Our judge caught 100%.

Declared (manifest)

{
  "name": "contract-analyzer-pro",
  "permissions": ["read:pdf"],
  "endpoints": ["ocr.analyzer-cdn.io"],
  "purpose": "OCR contracts and summarize."
}

Observed (runtime)

Static analysis

Regex, signatures, hashes.

What every other scanner runs.

The judge

An LLM reads each skill the way a reviewer would.

Catches the 67% that pattern-matching misses.

Runtime

Hooks into the agent at runtime.

Catches threats that weren't in the file when we scanned it.

Control, not just visibility

Set policy. Block at runtime. Update the fleet from one place.

Detection rules tab with the Repello Recommended active policy pack

Policies

Detection rules, allowlist, notification routing. Pack starters for SOC 2, NIST AI RMF, OWASP Top 10.

Runtime alert showing a blocked tool call

Runtime blocking

Repello's local proxy and native hooks intercept tool calls. Block known-bad patterns before they execute.

Fleet updates

Mismatched MCP versions across the fleet? Push the update through Repello's daemon, your MDM, or your EDR.

Most AI security tools tell you what’s wrong. We help you fix it.

Where scans run

Locally on the device. Skill bodies, manifests, and MCP configs never leave at Business+.

What leaves the device

Personal/Team: hashed indicators only, opt-in. Business+: nothing.

Tenant isolation

Each Business+ tenant fully isolated. One-way pull from threat corpus.

Deployment shapes

SaaS · single-tenant cloud · on-prem · air-gap.

Not an EDR replacement.

Sits beside CrowdStrike, SentinelOne, Defender, Trend.

Not a network proxy.

Scans run locally.

Not a single-vendor admin tool.

Sits above Anthropic's console and Cursor's admin.

How it gets on the laptop

No new agent to manage. Use the deployment infrastructure you already run.

Push via your existing EDR

CrowdStrike RTR · SentinelOne RemoteOps · Microsoft Defender Live Response · Trend Vision One Workbench · ThreatLocker allowlist

One-line script your IT team runs once.

MDM rollout

Jamf · Kandji · Intune · NinjaOne · Workspace ONE

Signed pkg + configuration profile points the app at your tenant. 15-minute setup.

Direct download

macOS DMG. Drag to Applications.

For champions evaluating before fleet rollout.

Once deployed, we also push MCP version updates, policy changes, and runtime configuration through the same channels you already trust: our daemon, your MDM, or your EDR’s remote response tool. Same install path, ongoing fleet control.
