Single gateway for all MCP clients is the right architectural call. Rust backend means it won't fall over under load. Config setup is a bit…

Centralizing MCP routing reduces attack surface breadth but makes the gateway a high-value single point of failure. Security posture depend…

03SECURITYWHAT WE CHECKED

Security flags foundOur static scan found signals worth reviewing before you trust this with an agent. See exactly what, per check, below.

Telemetry disclosureUndisclosed egress detected.Static checks found network calls the docs do not mention. Disclosed telemetry is common and fine, silent telemetry is the finding.

Security tierTier 1, Contained.No network access and no credentials. Runs entirely on its own. What tiers mean

Install-time hooks & dependencies1 finding

HIGHpackage.json — npm 'prepare' lifecycle hook: install hook runs a command that fetches from the network, pipes to a shell, or runs an encoded/inline-interpreter command: the arbitrary-code-on-install supply-chain vector.

Runs code / shell commands19 findings

MEDIUMapps/desktop/src/features/gateway/useGatewayControl.tsx:146 — Code-execution surface: a exec/spawn call site. The server can run commands on the host; review what it executes and whether any input reaches it.

MEDIUMapps/desktop/src/lib/api/gateway.ts:108 — Code-execution surface: a exec/spawn call site. The server can run commands on the host; review what it executes and whether any input reaches it.

INFOtests/e2e/wdio.conf.ts:19 — Code-execution call site (node child_process) in TEST code. Down-weighted to informational: this is the test exercising the server, not the server's runtime surface.

Prompt-injection passthrough3 findings

INFOtests/e2e/pages/BasePage.ts — HEURISTIC: this file both fetches external content and returns content as tool output, with no obvious sanitization. External text returned into tool output can carry instructions an agent obeys (prompt-injection passthrough). Confirm manually; this is a hint, not proof.

INFOtests/ts/components/App.test.tsx — HEURISTIC: this file both fetches external content and returns content as tool output, with no obvious sanitization. External text returned into tool output can carry instructions an agent obeys (prompt-injection passthrough). Confirm manually; this is a hint, not proof.

INFOscripts/take-screenshots.cjs — HEURISTIC: this file both fetches external content and returns content as tool output, with no obvious sanitization. External text returned into tool output can carry instructions an agent obeys (prompt-injection passthrough). Confirm manually; this is a hint, not proof.

Permission scope breadth1 finding

INFOtests/e2e/wdio.conf.ts — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.

How to read this: these are static checks over the source at a point in time. They catch the patterns above, not everything. Absence of a flag is not absence of danger, and a tool that runs cleanly can still behave differently once installed. We do not call any tool simply "safe". Runtime-behavior checks are the next layer we are adding.
