CAPEsolo 0.5.19

Standalone CAPEMON

Python GUI to run capemon in standalone VM. Provides a subset of CAPE (Configuration And Payload Extraction) processing and results.

• Create a Windows 10 VM that's suitable for running malware.
  • Use the CAPEv2 guest guide for configuration details.
  • https://capev2.readthedocs.io/en/latest/installation/guest/index.html
• Install Python in VM, tested on 64-bit Python versions 3.11 and 3.12, and add Python to path.
• Download and install both Microsoft Visual C++ Redistributables:
  • https://aka.ms/vs/17/release/vc_redist.x86.exe
  • https://aka.ms/vs/17/release/vc_redist.x64.exe
• Install CAPEsolo.
  • pip install CAPEsolo
• Snapshot your VM.

Quick Start

• Open an administrator command window.
• Type capesolo to run.

Alternatively, create a shortcut to CAPEsolo.exe, which will be in the Scripts subdirectory of same location as your python.exe file.

• Under Advanced, check 'Run as administrator'
• An icon file is available in the CAPEsolo install folder under site-packages.

Analysis results are found in C:\Users\Public\CAPEsolo\analysis.

• Can be configured in python-path\site-packages\CAPEsolo\cfg.ini

Revert the VM after each analysis.

MCP Server

• CAPEsolo includes an MCP server entrypoint for programmatic analysis workflows.
• Install project dependencies (including mcp) in your environment.

Run

• Start the server over stdio:
  • CAPEsolo-mcp
  • or python -m CAPEsolo.mcp_server

Available MCP Tools

• capesolo_analyze_sample
  • Submit a sample for analysis.
  • Key args: sample_path, package (Auto-detect by default), options, timeout, enforce_timeout.
• capesolo_analyze_password_zip
  • Submit a password-protected ZIP for analysis.
  • Key args: zip_path, optional zip_password (defaults to infected), optional archive_member_path (required when ZIP has multiple files), package, options, timeout, enforce_timeout.
  • ZIP extraction/decryption is handled by SFlock2.
• capesolo_get_job_status
  • Get job state (queued, running, completed, failed).
• capesolo_cancel_job
  • Request termination of a running job (same analyzer termination signal used by GUI Kill).
• capesolo_get_results
  • Return CAPEsolo JSON results using existing keys (target, behavior, signatures, payloads, configs, detections).
• capesolo_get_job_log_tail
  • Return the last N lines from analysis.log for a job.
• capesolo_render_html_report
  • Generate an HTML report from completed analysis.
• capesolo_list_payloads
  • List payload artifacts from analysis output.
• capesolo_list_dropped_files
  • List dropped files under analysis files output.
• capesolo_list_debug_logs
  • List debugger and analysis log artifacts.
• capesolo_update_yara
  • Update CAPE/community YARA rules.

Typical Workflow

1. Call capesolo_analyze_sample or capesolo_analyze_password_zip.
2. Poll capesolo_get_job_status until completed.
3. Call capesolo_get_results (and optionally capesolo_render_html_report).

Headless Single-Run CLI

• CAPEsolo supports a non-MCP single-run mode that reuses the same backend job runner as the MCP server.
• Run one analysis and exit:
  • CAPEsolo --headless-analyze "C:\path\sample.exe"
• Optional flags:
  • --package <name>
  • --options "key=value,key2=value2"
  • --timeout <seconds>
  • --enforce-timeout
  • --headless-json
  • --headless-html-report

MCP Client Config Examples

• Use these examples to connect CAPEsolo MCP server to common clients.
• Server command is:
  • CAPEsolo-mcp
  • or python -m CAPEsolo.mcp_server

Claude Desktop

• Add to Claude Desktop MCP config:

{
  "mcpServers": {
    "capesolo": {
      "command": "python",
      "args": ["-m", "CAPEsolo.mcp_server"],
      "cwd": "C:\\Users\\lkuca\\PycharmProjects\\CAPEsolo"
    }
  }
}

Cursor

• Add in Cursor MCP servers config:

{
  "mcpServers": {
    "capesolo": {
      "command": "CAPEsolo-mcp",
      "args": []
    }
  }
}

OpenCode

• Add in OpenCode MCP config:

{
  "mcpServers": {
    "capesolo": {
      "command": "python",
      "args": ["-m", "CAPEsolo.mcp_server"],
      "cwd": "C:\\Users\\lkuca\\PycharmProjects\\CAPEsolo"
    }
  }
}

Codex (Custom Host App)

• If you run Codex through a custom client/app, configure the app's MCP server map with:

{
  "mcpServers": {
    "capesolo": {
      "command": "CAPEsolo-mcp",
      "args": []
    }
  }
}

• The host app must support MCP tool calls and pass them through to the Codex model runtime.

PyCharm AI Assistant

• Open:
  • Settings -> Tools -> AI Assistant -> Model Context Protocol (MCP)
• Add JSON config:

{
  "mcpServers": {
    "capesolo": {
      "command": "python",
      "args": ["-m", "CAPEsolo.mcp_server"],
      "cwd": "C:\\Users\\lkuca\\PycharmProjects\\CAPEsolo"
    }
  }
}

Quick Connection Test

1. Start your MCP-enabled client with the config above.
2. Call capesolo_get_job_status with a fake id:
   • {"job_id":"test"}
3. Expected response pattern:
   • {"found": false, "error": "Job not found: test"}
