Key Features
  • • Semantic SAST with custom and community rules
  • • Supply-chain analysis for vulnerable and malicious dependencies
  • • Secrets detection with validation and remediation workflows
  • • Detection agents running continuously on live log streams with natural-language intent
  • • Response agents completing full investigations in seconds with evidence trails

Semgrep MCP - Pros & Cons

Pros

  • ✓Community Code and Supply Chain are available at $0 per contributor.
  • ✓One platform covers first-party code, dependencies, and secrets.
  • ✓Custom rules can encode organization-specific security policy.
  • ✓MCP brings findings into an active coding workflow.

Cons

  • ✗Teams starts at $30 per contributor monthly; Secrets is separately shown at $15.
  • ✗Static analysis findings still require triage and ownership.
  • ✗Custom rules need maintenance as code and frameworks change.
  • ✗Agent access creates another sensitive permission boundary.

Cotool - Pros & Cons

Pros

  • ✓Natural-language detection intent replaces brittle SIEM query syntax
  • ✓Self-improving: false positives automatically refine upstream detection rules
  • ✓Already in production at notable companies (Ramp, Elise AI) with 50K+ runs
  • ✓70% reduction in investigation and detection engineering time reported by early users
  • ✓Strong investor backing (a16z, YC) signals market confidence
  • ✓No-code agent builder makes custom automations accessible to security analysts

Cons

  • ✗Early-stage startup — small team (YC batch), limited track record vs established vendors
  • ✗Pricing not publicly available; enterprise sales process required
  • ✗Requires integration with existing log streams and security tooling
  • ✗Limited public documentation on supported log sources and SIEM migrations
  • ✗Not a replacement for full SIEM — focused on detection and response, not log storage
