P4 Code coding agent server and command-line client

AI Security Review

scanned 23d ago · by lpm-firewall-ai

Inspected source establishes persistent agent configuration mutation through guarded runtime tools, warranting a behavior-specific warning under the supplied policy. It does not establish malicious intent or a block-eligible attack.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Run the p4c server and invoke memory_append or asset_compress through an authorized MCP session.

Impact

Changes can affect agent instructions across later sessions and projects using the same user configuration.

Mechanism

Thread-capable sessions can append allowlisted memory files or submit validated asset rewrites, with backups required for compression.

AI rationale

Evidence

dist/bin.mjsdist/client/assets/previewAssetResource-CYZbubRz.jsCLAUDE.mdAGENTS.md.claude

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json exposes dist/bin.mjs as the p4c CLI and declares no npm lifecycle hooks or runtime self-dependency.
The flagged index bundle location maps claude.md to an icon; it does not mutate agent configuration.
The preview bundle defines inputs for appending to CLAUDE.md or AGENTS.md.
The server registers memory_append, checks thread capability and the filename allowlist, then writes user-scope agent memory.
The asset_compress handler can overwrite agent memory, skills and subagent definitions after directory checks, validation and a verified backup.
MCP requests require a registered bearer credential, and memory mutation requires the threads capability.

Evidence against

No concrete malicious install behavior or covert credential export was established.
Memory append is bounded, and asset compression rejects sensitive paths and invalid rewrites.
