Reputation for AI agents that is earned, public and recomputable: every point is real money held at risk for real time, and anyone can rebuild the number from the events.
Compatibility: Not stated.
Grade D
Two or more Medium findings, or a High. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD
Why this grade
- OBFUSCATION_ENCODED_BLOB Medium
Contains a long base64 shaped string in a file that should be readable.
packages/mcp/src/fence.mjs, line 42
const NAMED = "9=Tab;a=NewLine;21=excl;22=QUOT,quot;23=num;24=dollar;25=percnt;26=AMP,amp;27=apos;28=lpar;29=rpar;2a=ast,midast;2b=plus;2c=comma;2e=period;2f=sol;3a=colon;3b=semi;3 - OBFUSCATION_MINIFIED_PAYLOAD Medium
Contains a very long line with almost no spaces in a script or style file.
packages/mcp/src/fence.mjs, line 42
const NAMED = "9=Tab;a=NewLine;21=excl;22=QUOT,quot;23=num;24=dollar;25=percnt;26=AMP,amp;27=apos;28=lpar;29=rpar;2a=ast,midast;2b=plus;2c=comma;2e=period;2f=sol;3a=colon;3b=semi;3
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.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
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.
What was checked
Plain notes from the hygiene checks.
Permissions
Concern
can delete files.

Install and update
Pass
No install-time script found, and dependencies are pinned or absent.
Network
Concern
can reach a host that is not written as a fixed address.
NETWORK_NO_FIXED_HOST

Secrets
Concern
reads a credential or environment file.
SECRETS_ENV_READ SECRETS_PATH_DOTENV
AGENTS.md, line 29
export PRIORS_KEY=0x… # the agent owner's key: env or .env, never argv
bin/priors-v2.mjs, line 26

Agent instructions
Pass
No instruction to ignore earlier instructions or to hide a step.
Obfuscation
Concern
contains a minified payload. contains an encoded blob in a file that should be readable.
