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
  • No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
  • Known CVEs were checked across the 92 of 92 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass
  • 30 of 92 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability88
  • 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 1106 tokens (~85/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 Management100
  • No destabilizing schema changes in the last 30 days.Pass
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

MCP tools · 12 exposed · ~1,088 tokens

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 →

Tool Tokens
calendars_list ~35

Every calendar imported into this server: its name, where it came from, how many event definitions it holds and when it was imported.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

conflicts ~98

Every pair of events overlapping in time, with minutes they collide. Across all calendars unless one named, so a clashing work/family event is caught. Whole-day events reported separately. Free: 31 days; Pro: any window.

NameTypeReqDescription
calendarstring–One calendar name; default every imported calendar
fromstringyesFirst day, YYYY-MM-DD
tostringyesLast day, YYYY-MM-DD, included

No output schema declared.

No examples provided.

event_export ~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.

NameTypeReqDescription
calendarstring–With from/to: limit to one calendar
fromstring–First day, YYYY-MM-DD (alternative to ids)
idsarray–Event ids from events_list, events_search or next_event
out_pathstringyesWhere to write the .ics file
tostring–Last day, YYYY-MM-DD, included

No output schema declared.

No examples provided.

event_to_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.

NameTypeReqDescription
currencystring–Currency of the rate: EUR, USD, GBP, PLN, or the word the user said ('euros'). Without it the time-tracker falls back to USD.
event_idstringyesEvent id from events_list, events_search or next_event
projectstringyesProject or client the meeting is billed to
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 ~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.

NameTypeReqDescription
calendarstring–One calendar name; default every imported calendar
fromstringyesFirst day, YYYY-MM-DD
tostringyesLast day, YYYY-MM-DD, included
zonestring–Show local times in this zone or city instead of your own

No output schema declared.

No examples provided.

events_search ~94

Find events whose title, description, location or attendees contain a phrase. Searches every imported calendar. Without from/to it looks a year back and a year forward on Pro, and the free window either side of today.

NameTypeReqDescription
fromstring–First day, YYYY-MM-DD
querystringyesWords to look for, case-insensitive
tostring–Last day, YYYY-MM-DD, included

No output schema declared.

No examples provided.

free_busy ~159

Where the time actually went: merged busy blocks from the calendars named, and the gaps in your working hours where nothing is booked. Free/transparent events do not count as busy; whole-day events block the day.

NameTypeReqDescription
calendarsarray–Calendar names; default all of them
fromstringyesFirst day, YYYY-MM-DD
tostringyesLast day, YYYY-MM-DD, included
work_endstring–End of your working day, HH:MM, default 17:00
work_startstring–Start of your working day, HH:MM, default 09:00
zonestring–Zone the working hours and the output are in; default your own

No output schema declared.

No examples provided.

ics_forget ~42

Remove one imported calendar and the local copy of its .ics file. Nothing else is touched.

NameTypeReqDescription
namestringyesThe calendar name from calendars_list

No output schema declared.

No examples provided.

ics_import ~143

Call this tool to read a calendar export and keep it under a name. Give path (.ics file), text (contents), or url (public .ics/webcal feed; Pro). Google, Apple, Outlook exports read. Re-importing a name replaces it.

NameTypeReqDescription
namestringyesWhat to call this calendar, e.g. "work" or "family"
pathstring–Path to a .ics file on this machine
textstring–The .ics file contents, pasted
urlstring–Public https:// or webcal:// .ics feed. Fetched once, only because you asked; Pro feature

Install

How do I install the com.bestremotetools/calendar-ics-events-free-busy MCP server?

com.bestremotetools/calendar-ics-events-free-busy ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.
