Inkog vs Snyk agent-scan

Snyk inspects MCP tools at runtime. Inkog scans the code that calls them.

The Difference

Aspect	Snyk agent-scan	Inkog
Approach	Runtime MCP tool inspection	Static source code analysis
Finds	Tool description poisoning, prompt injection in metadata	Logic flaws, tainted data flows, missing oversight
When	Connects to running MCP servers	Scans code before deployment
Scope	MCP tool descriptions and metadata	Source code across 11 agent frameworks
Output	CLI findings	SARIF, JSON, compliance reports

What Snyk agent-scan Does

Snyk agent-scan connects to MCP servers and inspects their tool descriptions for:

Prompt injection hidden in tool descriptions
Tool poisoning (malicious instructions in metadata)
Suspicious tool capabilities

It answers: “Are the MCP tools my agent uses safe?”

What Inkog Does

Inkog scans your source code to find:

Infinite loops in agent control flow
Tainted user input flowing to SQL queries, shell commands, or LLM prompts
Missing human oversight for high-stakes operations
Missing iteration bounds and token limits
Compliance gaps against EU AI Act and NIST AI RMF

It answers: “Is my agent code safe?”

Snyk agent-scan checks the tools your agent connects to. Inkog checks the code that calls those tools.

Real Scenario

Your agent connects to a database MCP server:

Snyk agent-scan checks: Does the MCP server’s tool description contain prompt injection? Is the metadata tampered with?

Inkog checks: Does your code pass unsanitized user input through the MCP tool call? Is there an iteration limit? Is there human oversight for data mutations?

Both checks matter. A clean MCP server doesn’t help if your code sends tainted data to it.

Use Both

    steps:
      # Inkog: Scan agent source code
      - run: npx @inkog-io/cli scan . --output sarif
 
      # Snyk agent-scan: Inspect connected MCP tools
      - run: npx @anthropic-ai/agent-scan inspect

They’re complementary — not competing. Snyk agent-scan secures the tool supply chain. Inkog secures your application code.
