## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Can alter a shared AI-agent authorization control surface without the installing user's consent.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.2.5
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. Installation silently modifies FastMCP's OAuth consent implementation outside this package. Because resolution may find a hoisted dependency, the change can affect other FastMCP consumers in the project.

## Security analysis

### Published attack-surface review

- **Summary:** Installation silently modifies FastMCP's OAuth consent implementation outside this package. Because resolution may find a hoisted dependency, the change can affect other FastMCP consumers in the project.

- **Trigger:** npm postinstall

- **Impact:** Can alter a shared AI-agent authorization control surface without the installing user's consent.

- **Evidence paths:** package.json, scripts/patch-fastmcp-consent.mjs, dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-08T11:33:54.618Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** foreign OAuth consent-screen patching

- **Attack narrative:** On installation, the package locates FastMCP using Node's dependency resolution, scans its distribution chunks, and overwrites the OAuth consent-screen method. This is an unconsented postinstall mutation of a foreign, potentially hoisted AI-agent authorization surface. Although the replacement retains approve/deny controls and no credential exfiltration was found, the package should not modify another package's consent implementation during install.

- **Rationale:** The runtime MCP service is package-aligned, but its postinstall hook silently patches a third-party OAuth consent control surface. That install-time mutation is concrete and can extend beyond this package when FastMCP is hoisted.

- **Files touched:** package.json, scripts/patch-fastmcp-consent.mjs, img/logo.png, node\_modules/fastmcp/dist/\*.js, node\_modules/fastmcp/dist/\*.cjs

- **Network endpoints:** https://fonts.googleapis.com, https://fonts.gstatic.com

### Review decision

- **Verdict:** Malicious

- **Confidence:** 91.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/patch-fastmcp-consent.mjs in postinstall., The postinstall script resolves fastmcp via Node resolution, including a hoisted project dependency., scripts/patch-fastmcp-consent.mjs rewrites every matching fastmcp dist chunk's generateConsentScreen method., The replacement controls the OAuth approve/deny consent UI for FastMCP servers.

- **Evidence against:** The replacement retains explicit approve and deny controls and escapes displayed consent values., No source evidence of credential harvesting, shell execution from postinstall, or outbound exfiltration., dist/index.js uses supplied Spidra credentials only to operate its documented MCP service.
