Semgrep MCP Server brings static application security testing (SAST) directly into your AI agent workflows through a single hosted MCP endpoint. Instead of manually running Semgrep scans in a terminal or CI job and copy-pasting results into a ticket, any AI agent — Claude, GPT, Gemini, or a custom-built assistant — can call the same standardized MCP interface to scan a repository, snippet, or diff for security vulnerabilities, bugs, and anti-patterns the moment code changes. This makes Semgrep a natural fit for teams that want continuous, agent-driven code review without duplicating credentials or tool configs across every AI client they use.

Under the hood, this MCP server wraps Semgrep's static code analysis engine and exposes its scanning capabilities as callable tools: rule-based pattern matching across dozens of languages, OWASP-style vulnerability detection, secret and hardcoded-credential checks, and custom rule execution for org-specific coding standards. Because it's hosted and managed by BusinessMCP, you don't need to provision your own Semgrep infrastructure, manage rule updates, or maintain a separate integration for each AI provider — you connect it once through your company's unified /api/mcp endpoint (Bearer mcph_* key) and every downstream agent inherits the same access, guardrails, and audit trail.

This is where the value compounds: Semgrep doesn't have to live in isolation. Paired with BusinessMCP's business-intelligence dashboard, security findings surface alongside the rest of your operational data — ad spend, revenue, database health, and other connected tools — so engineering leaders and non-technical stakeholders alike can see vulnerability trends without digging through separate security dashboards. Teams commonly use this setup to let a coding agent triage pull requests for injection flaws, insecure deserialization, or SSRF risks before a human reviewer even opens the diff, or to have an AI assistant explain a flagged anti-pattern in plain language during a code walkthrough.

Because the server is model-agnostic and cookieless/GDPR-friendly, it fits cleanly into regulated environments and multi-agent setups where you can't guarantee which LLM vendor a given workflow will use. Security teams evaluating a static code analysis MCP server for AI agents, DevSecOps engineers automating vulnerability scanning in agentic pipelines, or platform teams looking to centralize SAST tooling across multiple AI copilots will find this integration reduces setup friction considerably — one credential, one endpoint, and consistent scan results regardless of which assistant initiated the request.

Whether you're bolting security review onto an existing AI coding assistant, building an autonomous code-review agent, or simply want vulnerability scanning results to feed into your broader business intelligence view, the Semgrep MCP Server turns static analysis into an agent-callable capability rather than a standalone CLI step — hosted, unified, and ready to plug into your existing BusinessMCP setup alongside your other tools and data sources.

Just say it in a thread

No configs, no docs. Once connected, these are the kinds of messages your agents act on.

"Run a full semgrep static analysis scan against a given repository or codebase path — and give me the highlights."

"Analyze a code diff or pull request for newly introduced vulnerabilities and anti-patterns for me, then post a summary in the thread."

"Check code for hardcoded credentials, api keys, and other exposed secrets and flag anything that needs my approval."

What teams use it for

  • Have a coding agent scan a pull request for security vulnerabilities before human review
  • Run automated SAST checks on a repo as part of an AI-driven CI/CD pipeline
  • Ask an assistant to explain a flagged anti-pattern or vulnerability in plain language during a code walkthrough
  • Enforce custom, org-specific security rules across every AI agent touching the codebase
  • Surface recurring vulnerability trends in the BusinessMCP BI dashboard alongside other engineering metrics

Frequently asked questions

What does the Semgrep MCP Server actually scan?

It runs Semgrep's static analysis engine against source code to flag security vulnerabilities, bugs, hardcoded secrets, and anti-patterns using built-in and custom rule sets.

Can multiple AI agents use the same Semgrep integration?

Yes — since it's hosted behind a single /api/mcp endpoint with a Bearer mcph_* key, any connected agent (Claude, GPT, Gemini, or custom) can call the same scanning tools without separate setup.

Does this replace running Semgrep in CI?

It can complement or replace manual CI scanning steps by letting AI agents trigger scans on demand, though many teams run both for full pipeline coverage.
