Overview

Description from the maker (original English)

Code intelligence MCP server: call graphs, type inference, and symbol search for Python/Go.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "pathfinder": {
      "command": "uvx",
      "args": [
        "codepathfinder",
        "serve",
        "--project",
        "."
      ]
    }
  }
}

Run this in your terminal

claude mcp add pathfinder -- uvx codepathfinder serve --project .

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "pathfinder": {
      "command": "uvx",
      "args": [
        "codepathfinder",
        "serve",
        "--project",
        "."
      ]
    }
  }
}

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.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "pathfinder": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "codepathfinder",
        "serve",
        "--project",
        "."
      ]
    }
  }
}

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.

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

Common questions

Is Code Pathfinder 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (2.1.1) reached the registry 6 months ago.

Which apps can use it?

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

What can I use instead?

Open-source SAST engine that traces vulnerabilities across files and functions

Website · Docs · Rule Registry · MCP Server · Blog


Quick Start

Install:

brew install shivasurya/tap/pathfinder

Scan a Python project (rules download automatically):

pathfinder scan --ruleset python/all --project .

Scan Dockerfiles:

pathfinder scan --ruleset docker/all --project .

No config files, no API keys, no cloud accounts. Results in your terminal in seconds.


What is Code Pathfinder?

Code Pathfinder is an open-source static analysis engine that builds a graph of your codebase and traces how data flows through it. It parses source code into Abstract Syntax Trees, constructs call graphs across files, and runs taint analysis to find source-to-sink vulnerabilities that span multiple files and function boundaries.

v2.0 introduces cross-file dataflow analysis: trace user input from an HTTP handler in one file through helper functions and into a SQL query in another file. This is the kind of analysis that pattern-matching tools miss entirely.

Cross-File Taint Analysis

Most open-source SAST tools operate on single files. Code Pathfinder v2.0 tracks tainted data across file boundaries:

app.py:5    user_input = request.get("query")     ← Source: user-controlled input

↓ calls db.py:12 cursor.execute(query) ← Sink: SQL execution

The engine builds a Variable Dependency Graph (VDG) per function, then connects them through inter-procedural taint transfer summaries. When user_input flows into a function parameter in another file, the taint propagates through the call graph to the sink.

How It Works
Source Code → Tree-sitter AST → Call Graph → Variable Dependency Graph → Taint Analysis → Findings

↓ Inter-procedural Taint Summaries (cross-file flows)

  1. Parse: Tree-sitter builds ASTs for Python, Dockerfiles, and Docker Compose files
  2. Index: Extract functions, call sites, parameters, and assignments into a queryable call graph
  3. Analyze: Build VDGs per function, resolve inter-procedural flows, run taint analysis
  4. Detect: Python-based security rules query the graph to find source-to-sink paths
  5. Report: Output findings as text, JSON, SARIF (GitHub Code Scanning), or CSV

MCP Server for AI Coding Assistants

Code Pathfinder runs as an MCP server, giving Claude Code, Cursor, Cline, and other AI assistants access to call graphs, data flows, and security analysis. More context than LSP, focused on security and code structure.

pathfinder serve --project .

The MCP server exposes tools for querying the code graph: find callers/callees, trace data flows, search for patterns, and run security rules — all available to the AI assistant during code review or development.

Write Custom Rules

Security rules are Python scripts using the PathFinder SDK. Define sources, sinks, and sanitizers — the dataflow engine handles the analysis.

Here's a real rule from the repo (PYTHON-DJANGO-SEC-001) that detects SQL injection in Django:

from codepathfinder import calls, flows, QueryType

from codepathfinder.presets import PropagationPresets

class DBCursor(QueryType): fqns = ["sqlite3.Cursor", "psycopg2.extensions.cursor"] match_subclasses = True

@python_rule( id="PYTHON-DJANGO-SEC-001", name="Django SQL Injection via cursor.execute()", severity="CRITICAL", cwe="CWE-89", ) def detect_django_cursor_sqli(): return flows( from_sources=[ calls("request.GET.get"), calls("request.POST.get"), ], to_sinks=[ DBCursor.method("execute").tracks(0), calls("cursor.execute"), ], sanitized_by=[calls("escape"), calls("escape_string")], propagates_through=PropagationPresets.standard(), scope="global", # cross-file taint analysis )

# Run your custom rules

pathfinder scan --rules ./my_rules/ --project .

Explore all 190 rules in the rules/ directory or browse the Rule Registry. See the rule writing guide and dataflow documentation to write your own.
