Open in VS Code

Or copy the settings yourself

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

FRAME_LLM_BASE_URL env
Base URL of an OpenAI-compatible LLM endpoint for the AI detection, triage, fix and exploit features.
FRAME_LLM_API_KEY secret env
API key for the LLM endpoint, when the endpoint requires one.
FRAME_LLM_MODEL env
Model name to request from the LLM endpoint.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Frame MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: FRAME_LLM_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

frame-mcp

mcp-name: io.github.lambdasec/frame-mcp

An MCP server that exposes the Frame security scanner to any MCP client, so a coding agent can scan code, verify fixes, and reason about vulnerabilities over stdio.

Frame combines taint analysis with separation logic verification to find data-flow vulnerabilities (SQL injection, command injection, path traversal, and more), and checks each reported path with a solver. This package wraps the frame command line program as MCP tools. It launches frame as a subprocess with an explicit argument list, never a shell, and prefers the frame executable installed next to the running Python interpreter.

Install

Run directly with uvx (no separate install step):

uvx frame-mcp

Claude Code

claude mcp add frame -- uvx frame-mcp

Codex

Add this stanza to ~/.codex/config.toml:

[mcp_servers.frame]

command = "uvx" args = ["frame-mcp"]

Cursor

Create .cursor/mcp.json:

"mcpServers": { "frame": { "command": "uvx", "args": ["frame-mcp"] } } }

VS Code

Create .vscode/mcp.json:

"servers": { "frame": { "type": "stdio", "command": "uvx", "args": ["frame-mcp"] } } }

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json under the mcpServers key:

"mcpServers": { "frame": { "command": "uvx", "args": ["frame-mcp"] } } }

Gemini CLI

Add to ~/.gemini/settings.json under the mcpServers key:

"mcpServers": { "frame": { "command": "uvx", "args": ["frame-mcp"] } } }

Zed

Add to Zed settings.json under context_servers:

"context_servers": { "frame": { "command": { "path": "uvx", "args": ["frame-mcp"] } } } }

Tools

Tool	Purpose	Read only
`scan`	Scan a file or directory for vulnerabilities and return findings as JSON; `ai` adds LLM detection and triage, `hunt_authz` the agentic authorization hunt.	yes
`write_baseline`	Scan a path and record the findings as a baseline file.	no
`verify`	Re-scan the files behind earlier findings and report whether each is fixed.	yes
`fix`	Generate and verify fixes for findings. Returns a diff by default.	no
`exploit`	Drive an agent to exploit a live, authorized target.	no
`packs_list`	List the framework packs a scan would load.	yes
`packs_check`	Validate framework pack files.	yes
`solve`	Check a separation logic entailment `P \	- Q`.	yes

A security-review prompt chains scan (with the AI layer), verify, and an offer to fix.

AI features and environment variables

The scan tool with ai=true, along with fix and exploit, call an LLM through an OpenAI-compatible endpoint. Configure it with these environment variables in the MCP client that launches the server:

Variable	Purpose
`FRAME_LLM_BASE_URL`	Base URL of the LLM endpoint, for example a local server or a hosted API.
`FRAME_LLM_API_KEY`	API key for the endpoint, when it requires one.
`FRAME_LLM_MODEL`	Model name to request.

These are inherited from the server process environment and forwarded to each frame subprocess. Every other setting (streaming, timeouts, agent budgets, the hunt's budgets) is a key of the [llm] / [hunt] tables in the project's .frame.toml, which each frame command reads. The plain scan (taint analysis plus verification) needs none of them.

Exploit authorization

The exploit tool drives an autonomous agent that sends live traffic to a target. Run it only against systems you own or are explicitly authorized to test. Unauthorized testing of systems you do not control may be illegal.
