Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security23
- Malware scan not yet available for this package.Unverified
- Known CVEs were checked across the 96 of 96 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- 31 of 96 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 2 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability87
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 1225 tokens (~94/item across 13 items; 12 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "ics_forget" implies "remove" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
calendars_list List imported calendars ~54
List imported calendars: name, event-definition count, size, source, import time and free-tier use of the 2 slots. It also names stored .ics files with no calendar row. With none it prints the export steps.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
conflicts Find double bookings ~95
Find double bookings: every PAIR of timed events that overlap, with the minutes they collide, across all calendars unless you name one. Whole-day events are reported apart. Free: 31 days. free_busy shows gaps.
| Name | Type | Req | Description |
|---|---|---|---|
| calendar | string | – | One calendar name; default every imported calendar |
| from | string | yes | First day, YYYY-MM-DD |
| to | string | yes | Last day, YYYY-MM-DD, included |
No output schema declared.
No examples provided.
event_export Export events to a .ics file ~136
Call this tool to write chosen events to a new .ics file you can send or import elsewhere. Pass either ids (from events_list) or a from/to window. Times are written in UTC so the file lands correctly in any client.

event_to_time_entry Turn a meeting into a time entry ~155
Take one event and return the exact arguments for the time-tracker's entry_add, so a meeting that already happened becomes billable time without retyping it. Writes nothing: pass the JSON straight to entry_add.
| Name | Type | Req | Description |

| currency | string | – | Currency of the rate: EUR, USD, GBP, PLN, or the word the user said ('euros'). Without it the time-tracker falls back to USD. |

| rate | – | – | Hourly rate for this entry; a number (120) or the words the user said ('120 euros an hour') |
No output schema declared.
No examples provided.
events_list List events in a window ~115
Every event between two dates, recurring expanded to occurrences, sorted by start. Times shown in your zone (profile's, else this machine's) unless zone passed. Each id works for event_export or event_to_time_entry.
| Name | Type | Req | Description |
|---|---|---|---|
| calendar | string | – | One calendar name; default every imported calendar |

|---|---|---|---|
| from | string | – | First day, YYYY-MM-DD |
| query | string | yes | Words to look for, case-insensitive |
| to | string | – | Last day, YYYY-MM-DD, included |
No output schema declared.
No examples provided.
free_busy Busy blocks and free windows ~159
