A Why this grade threat 100 − adoption risk = 93/100

The grade answers one question — how safe is this server for you to adopt — so it is computed in two auditable stages. Nothing below is an opinion or an LLM's guess; every line is a real term the deterministic engine applied, and the same input always yields the same number.

1. Threat score — 100 − 0 = 100. What the published surface and source actually contain:

The deterministic scan raised no scored threat in the surface it inspected — the threat score stayed at 100. Capability observations and advisory notes are recorded but never lower it.

2. Client adoption risk — 100 − 7 = 93. Three small, subtract-only factors that reflect your risk in adopting it — a clean scan proves less on a powerful, unverified or barely-inspectable package, so the grade says so plainly:

PointsAdoption-risk factor
−6 capability blast radius (high) — client exposure if the model is manipulated
−1 publisher verification (public source) — no provenance, but the source is public and inspectable

Capability observations and info notes are shown under Findings but never scored. Open any row's finding below for the file, line and evidence behind a deduction.

Findings 9

high Shell/command execution in server code (dist/cli/tui/utils/clipboard.js)MTC-SRC-002

In the server's implementation (`dist/cli/tui/utils/clipboard.js:4`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: rt { spawn } from "node:child_process"; /** * Copy text to the system clipboard. * Uses pbcopy on macOS, xclip on Linu

Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

high Shell/command execution in server code (dist/cli/tui/utils/open-external.js)MTC-SRC-002

This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: rt { spawn } from "node:child_process"; const TEMP_DIR_NAME = "procsi-exports"; /** * Get the platform-specific command

In the server's implementation (`dist/cli/tui/utils/terminal-size.js:2`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: spawnSync } from "node:child_process"; function isPositiveInteger(value) { return typeof value === "number" && Numb

high Shell/command execution in server code (dist/shared/browser.js)MTC-SRC-002

This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

high Shell/command execution in server code (dist/shared/daemon.js)MTC-SRC-002

In the server's implementation (`dist/shared/daemon.js:3`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

high Shell/command execution in server code (dist/shared/process-name.js)MTC-SRC-002

In the server's implementation (`dist/shared/process-name.js:5`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

medium Untrusted input can drive an external actionMTC-FLOW-005

Untrusted-input tools ([procsi_list_requests, procsi_get_request]) co-exist with external-action tools ([procsi_list_requests, procsi_get_request, procsi_count_requests, procsi_clear_requests, procsi_replay_request, procsi_save_request, procsi_unsave_request]). A prompt injection could cause unwanted external actions, though no direct sensitive-data leak path was found.

Evidence: untrusted [procsi_list_requests, procsi_get_request] → sinks [procsi_list_requests, procsi_get_request, procsi_count_requests, procsi_clear_requests, procsi_rep

Fix: Require confirmation for state-changing/egress actions triggered after processing untrusted content.

Location: flow procsi_list_requests → procsi_list_requests

medium Dynamic module load from a non-literal (dist/daemon/interceptor-loader.js)MTC-SRC-005

In the server's implementation (`dist/daemon/interceptor-loader.js:123`): Loading a module chosen at runtime (from a variable) can pull in and run attacker-influenced code paths. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: const mod = await jiti.import(filePath); const { interceptors: extracted, errors } = extractInterceptor

medium Dynamic module load from a non-literal (dist/overrides/node.js)MTC-SRC-005

In the server's implementation (`dist/overrides/node.js:51`): Loading a module chosen at runtime (from a variable) can pull in and run attacker-influenced code paths. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
