How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security99
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
  • 2 of 16 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency96
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Cryptographically verified build provenance (signed, bound to daedalus/mcp-rs232). View diagnostics → Pass
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 220 days ago).Pass
  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability85
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 412 tokens (~58/item across 7 items; 6 tools + 1 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass

MCP tools · 6 exposed · ~374 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the io.github.daedalus/mcp-rs232 server?

io.github.daedalus/mcp-rs232 is listed in the public MCP registry as io.github.daedalus/mcp-rs232. An MCP server that exposes RS232 serial port connectivity. This page covers its PyPI package (mcp-rs232).

Is the io.github.daedalus/mcp-rs232 server safe to use?

io.github.daedalus/mcp-rs232 scores 96 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.daedalus/mcp-rs232 server expose?

io.github.daedalus/mcp-rs232 exposes 6 tools: list_ports_tool, open_port, close_port, read_port, write_port, get_port_config. Their descriptions and schemas cost roughly 374 tokens of context every time the server is loaded.

Is the io.github.daedalus/mcp-rs232 server still maintained?

io.github.daedalus/mcp-rs232 is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the io.github.daedalus/mcp-rs232 server under?

io.github.daedalus/mcp-rs232 declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
