Scheduling is one of the highest-ROI workflows to hand off to an agent. Cal.com is a solid platform and this covers bookings, event types,…

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 & dependenciesno flags

Code that runs when you install it, before you ever call a tool.

Runs code / shell commandsno flags

Whether the server can execute commands on your machine.

Secrets & credentials2 findings

HIGHapp.py:28 — A secret read into 'CALCOM_API_KEY' at line 27 reaches a log/print sink at line 28 within the same function: a credential may leak/exfiltrate. Confirm the data path.

INFOapp.py:27 — Reads a secret-shaped environment variable. Ordinary for a credentialed server; recorded for completeness.

Network calls out1 finding

MEDIUMapp.py:29 — Hardcoded external endpoint 'api.cal.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

Prompt-injection passthrough1 finding

INFOapp.py — 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 breadthno flags

How much access it asks for versus what its job needs.

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.
