How do Endor Labs and Semgrep cover AI code and coding assistants?

Endor Labs: AURI inventories coding agents, models, MCP servers and skills, and the MCP server installs into Cursor, Claude Code, VS Code with Copilot, Codex and Antigravity. AI SAST traces dataflow across repositories and pull requests.

Semgrep: Semgrep Guardian scans inside Claude Code, Cursor and Windsurf as code is written; org-wide discovery of assistants or MCP servers is not described and Copilot is not listed.

Assistants named on their public pages: Endor Labs: Claude Code, Cursor, GitHub Copilot and OpenAI Codex; Semgrep: Claude Code, Cursor and Windsurf.

Where do their controls run on the developer machine?

Endor Labs: Runs locally through an MCP server (npx endorctl ai-tools mcp-server) and AURI agents that run inside Claude Code, Cursor, OpenAI Codex and Google Antigravity on customer infrastructure; an endpoint application and tamper resistance are not described.

Semgrep: Guardian runs on the developer machine as an MCP server, hooks on every file write and skills; tamper resistance is not described.

How much control does the security team get?

Endor Labs: AURI applies policy at the moment of action with an audit trail, and mutating agent actions sit behind approval gates; scoping policy by team or machine is not described.

Semgrep: Guardian enforces checks per agent, but the pages reviewed show no central inventory or policy over which agents and MCP servers may run.

How do they fit the developer's workflow?

Endor Labs: The free Developer tier runs locally with no account.

Semgrep: Free for up to 10 contributors and 10 private repos, with VS Code and JetBrains support.

How do they fix and prioritize findings?

Endor Labs: Reachability across dependencies, containers and code, and AURI agents write SAST fixes and open SCA upgrade pull requests behind approval gates. Ingestion of third-party scanner findings is not confirmed.

Semgrep: Semgrep Assistant auto-triages findings, and remediation guidance appears in pull requests and IDEs.

How do they compare on price?

Endor Labs: free tier: Yes: Developer tier, local, no account; lowest published paid option: Contact sales; pricing unit: Contributors with commits in the last 90 days.

Semgrep: free tier: Yes: up to 10 contributors; lowest published paid option: $30 per contributor per month (Code or Supply Chain); $15 (Secrets); pricing unit: Contributor.
