Latest receipt: 3 of 8 checks flagged — the findings below are the record. SHA-256 of the exact bytes scanned: 51552fa66eee9852eb40f5bad68319df90800e88c399c4f404562c570216c05b · 4561 bytes · scanned 2026-10-27T12:18:26.260Z · scanner resource-scan-v1 · ledger entry 1493.

Analysis is static only: the bytes were read as text and were never executed, installed or run. Nothing was fetched from behind a login.

Checks (latest receipt)

• Outbound network references — flag

  The scanned bytes reference outbound network activity to these domains: github.com, img.shields.io, modelcontextprotocol.io, py.sdk.modelcontextprotocol.io, pypi.org, www.python.org. Any resource that reaches the network can send data out as well as bring data in; the findings name what the bytes reference, and the reader decides whether that fits the resource's stated purpose.

  Evidence: domain: github.com; domain: img.shields.io; domain: modelcontextprotocol.io; domain: py.sdk.modelcontextprotocol.io; domain: pypi.org; domain: www.python.org

• Credential and environment access — pass

  No credential or environment access patterns were found in the scanned bytes.

• Install and postinstall hooks — pass

  No install or postinstall hooks were found in the scanned bytes.

• Obfuscation and encoded payloads — pass

  No obfuscation or encoded-payload signs were found in the scanned bytes.

• Shell-outs and download-and-execute — flag

  The scanned bytes contain shell-out or download patterns: shell invocation from Python (subprocess, os.system, Popen). Code that runs shell commands acts with the full permissions of whoever runs it.

  Evidence: shell invocation from Python (subprocess, os.system, Popen)

• Permission declarations vs behavior — flag

  The bytes show network behavior, and no permissions declaration was found in the scanned bytes to compare it against.

  Evidence: behavior: network

• Known-bad indicators — pass

  None of the scanner's published known-bad indicator patterns matched the scanned bytes.

• Provenance facts (weak signals) — pass

  Provenance facts, labeled weak signals — they say where the bytes sit, not what the bytes do: source host: github.com; repository: modelcontextprotocol/python-sdk; bytes scanned: 4561; fetched from: https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/HEAD/README.md.

  Evidence: source host: github.com; repository: modelcontextprotocol/python-sdk; bytes scanned: 4561; fetched from: https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/HEAD/README.md

History

Every receipt for this artifact so far names the same SHA-256: the bytes have not changed between scans.
