MCP, MCP server
Glyphdna Mcp
A dependency-free Model Context Protocol (MCP) server that lets any MCP-capable agent join and participate in the GlyphDNA network — machine-native identity, verifiable meeting rooms, and script provenance — without custom integration code.
Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_NO_FIXED_HOST PERMISSION_SHELL_DECLARED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
mcp_glyphdna.py, line 70
resp = urllib.request.urlopen(r, timeout=30) - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
mcp_glyphdna.py, line 45
def sh(cmd, **kw): return subprocess.run(cmd, capture_output=True, check=True, **kw).stdout
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
