Local serverstdioPython

What is the MCP MCP server?

MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP server exposing Capstone 5.0.7 disassembly framework.

What you get

MCP server that exposes Capstone 5.0.7 disassembly framework functionalities as tools and resources, enabling LLMs to perform binary disassembly, reverse engineering, and instruction analysis.

What the assistant can call

Once MCP is connected, these are the calls the assistant has available:

  • get_version — Get Capstone version
  • check_support — Check architecture support
  • list_architectures — List all architectures
  • disasm — Full disassembly with details
  • disasm_lite — Lightweight disassembly
  • disasm_quick — Quick disassembly
  • get_architectures — All architecture constants
  • get_modes — All mode constants
  • get_options — All option constants
  • get_operands — All operand type constants
  • get_groups — All instruction group constants
  • get_errors — All error constants

Setting it up

The server ships on PyPI as mcp-capstone, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Choosing this one

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP's toolset — get_version, check_support, list_architectures and 9 more — is a fair guide to whether it matches your workflow. It is maintained by daedalus; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 12 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch MCP.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp mcp server does with a few real requests.

How to install the MCP MCP server

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

Add to claude_desktop_config.json, then restart Claude Desktop.

Example prompts to try

  • Use MCP to get version.
  • Use MCP to check support.
  • Use MCP to list architectures.

Frequently asked questions

It connects MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 12 tools (get_version, check_support, list_architectures, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP directly.
