  "works": "The plugin's own HTTP/MCP server code, built for Linux with stand-in Windows calls and a fake paused debugger, started a session with the official MCP Python SDK client (server 'x64dbg-MCP Server' 1.6, protocol 2024-11-05) over both Streamable HTTP and SSE. tools/list returned 80 tools; Echo, GetDebugState and Disassemble (integer address) returned results with the debugger state line, and an SSE client received a pushed event. A missing token, a wrong token or a lowercase 'bearer' scheme got 401, and a very large Content-Length sent before auth no longer crashed the server. Zig 0.14.0 (the CI-pinned version) builds it.",
  "breaks": "Blocked: real debugging still needs x64dbg on Windows. Confirmed end to end: control characters in tool text are written unescaped, so the reply is invalid JSON and the SDK client fails to parse it. New: a string request id containing a control character is echoed as invalid JSON, and integer ids above the signed 64-bit range come back as null; requests over 64 KB are cut off and answered 'Parse error'; the Content-Length header is matched only in two exact spellings, so a body arriving in a later packet under another spelling also gets 'Parse error'; a bind address that is not a numeric IPv4 address (for example a hostname) is not rejected and the server listens on all interfaces while the log shows the typed value; an overlong numeric octet in the bind address crashes the server at start; unknown tools come back as JSON-RPC errors rather than isError tool results. The v1.6 release plugin files could not be rebuilt identically from the tag, and there is no release workflow; CI builds ReleaseFast while the README says ReleaseSafe. Docs: the README gives 84 and 72 tools (80 at runtime), a default bind of 0.0.0.0 (127.0.0.1 at runtime) and Zig 0.16-dev or later (0.14.0 builds); the manifest still says 1.0.0.",

  "security_flags": [
   "High-privilege by design and documented: it can run any debugger command, attach to processes, read and write their memory, and write files. The access token is stored in plain text and the transport is plain HTTP, with no security policy file; keep it bound to 127.0.0.1 (the code default) and only debug programs you trust. Two earlier public advisories (missing authentication, fixed in 1.0/1.1; a crash before the token check, fixed in 1.2) are fixed in this version. Prescreen: caution, no sign of malware, not on the malware list, no install scripts. No non-public flaw found.",
   "Same documented high-privilege design as the first run (any debugger command, process memory read and write, file writes; plain-text token over plain HTTP). New caution: the bind-address setting is not validated, so a value that is not a numeric IPv4 address can leave the server reachable on all network interfaces while the log suggests otherwise; set a numeric address such as 127.0.0.1 and confirm what the port is bound to. The release plugin files could not be rebuilt identically from the tagged source, so build from source if you need a binary you can verify. No sign of malware; token checks held in this test."
