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 2, Networked.Reaches the live web, but needs no secrets. What tiers mean
Install-time hooks & dependencies1 finding
HIGHpackage.jsonnpm '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 commands10 findings
MEDIUMsrc/tools/handlers/pipeline/pipeline-ubt-discovery.ts:1Code-execution surface: a node child_process call site. The server can run commands on the host; review what it executes and whether any input reaches it.
MEDIUMsrc/tools/handlers/pipeline/pipeline-ubt-runner.ts:1Code-execution surface: a node child_process call site. The server can run commands on the host; review what it executes and whether any input reaches it.

INFOsrc/utils/commands/command-validator.test.ts:44Code-execution call site (exec/spawn) in TEST code. Down-weighted to informational: this is the test exercising the server, not the server's runtime surface.

MEDIUMsrc/tools/handlers/foundation/arguments/handler-url-validation.test.ts:30Hardcoded external endpoint 'user'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

Prompt-injection passthrough1 finding
INFOtests/test-runner.mjsHEURISTIC: 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/test-runner.mjsHEURISTIC: 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.
