About Semgrep MCP Server
Connect the Semgrep AppSec platform directly to your AI agent to radically accelerate code security triaging. Instead of forcing developers to jump between their IDE and the Semgrep dashboard, empower your AI to pull 'Findings', analyze the vulnerable syntax, and instantly close false positives.
Claude Code registers Semgrep as an MCP server in a single terminal command. Once connected, Claude Code discovers all 10 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Semgrep data drives decisions without human intervention.
What you can do
- Triage Findings (Bugs) — Instruct the agent to grab the latest CI vulnerability findings and immediately push a status update to mark it as fixed, ignored, or mitigated (
update_finding_status) - Rule Management — Request the AI to look at a newly discovered bad coding pattern and command it to write and deploy a matching custom semantic rule (
create_rule) to your organizational deployment - Project & Deployment Scoping — Map out all repositories running Semgrep actions and check their overarching security health scores in milliseconds
- Comprehensive Forensics — Fetch granular SCA and SAST semantic flaw definitions, including exact snippets, CVE links, and the specific bad lines causing the trigger
The Semgrep MCP Server exposes 10 tools through the Vinkius. Connect it to Claude Code in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use Claude Code with the Semgrep MCP Server
Claude Code provides unique advantages when paired with Semgrep through the Model Context Protocol.
Single-command setup: `claude mcp add` registers the server instantly. no config files to edit or applications to restart
Terminal-native workflow means MCP tools integrate seamlessly into shell scripts, CI/CD pipelines, and automated DevOps tasks
Claude Code runs headlessly, enabling unattended batch processing using Semgrep tools in cron jobs or deployment scripts
Built by the same team that created the MCP protocol, ensuring first-class compatibility and the fastest adoption of new protocol features
Semgrep + Claude Code Use Cases
Practical scenarios where Claude Code combined with the Semgrep MCP Server delivers measurable value.
CI/CD integration: embed Semgrep tool calls in your deployment pipeline to validate configurations or fetch secrets before shipping
Headless batch processing: schedule Claude Code to query Semgrep nightly and generate reports without human intervention
Shell scripting: pipe Semgrep outputs into other CLI tools for data transformation, filtering, and aggregation
Infrastructure monitoring: run Claude Code in a cron job to query Semgrep status endpoints and alert on anomalies
Semgrep MCP Tools for Claude Code (10)
These 10 tools become available when you connect Semgrep to Claude Code via MCP:
create_rule
Allows developers to forbid project-specific bad patterns securely and continuously across the enterprise repositories. Create a customized Semgrep security rule within the platform
delete_rule
Delete a custom Semgrep security rule from the deployment
get_finding_details
Explains the exact malicious code block, suggests semantic fixes, states whether it is blocking PRs in CI, and links to CVE data (if an SCA supply chain defect). Get atomic details for a specific Semgrep flaw
get_metrics
Typically consumed to render executive security dashboards. Get AppSec metrics and compliance stats for Semgrep
get_project
Search for a precise Semgrep project by exact repository name
list_deployments
The primary key is the deployment slug identifier. Almost all subsequent API operations targeting rules, projects, or findings will require this deployment slug to define the scope. List Semgrep organizational deployments
list_findings
Findings provide snippet details, file line numbers, severity, and rule types. Fetch global static analysis security findings for a deployment
list_projects
Projects maintain a link between developers and static security scan outputs over time. List Semgrep projects (repositories) monitored in a deployment
list_rules
The rules are structured YAML definitions that search for semantic anti-patterns in codebases (e.g., unparameterized SQL queries, hardcoded AWS keys). List Semgrep semantic rules deployed globally
update_finding_status
Valid states generally include active, fixed, false_positive, ignored, mitigated. Resolving findings through this API cleans up the developer experience when managing compliance queues. Mark a Semgrep finding state (e.g., fixed, false positive)
