How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security80
Transport & Reachability100
Schema Quality & AI Usability86
  • 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
  • Context-footprint check failed: tool/resource definitions use about 3397 tokens (~117/item across 29 items; 19 tools + 10 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage96
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 88% of tool parameters carry a description.Partial
  • Structured output schemas are declared (21% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
  • An AI judge read all 21 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
Install

How do I install the Rhylthyme MCP server?

Rhylthyme is a hosted endpoint at https://mcp.rhylthyme.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 19 exposed · ~2,441 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
analyze_schedule ~307

Put a program on the clock: each step's start and end, total length, the critical path and what gates it, resource conflicts, slack per track. Pass finishAt to answer 'when do I start X so everything is ready at 6pm?'. Pure computation. With `history` (or `program_id`) it also predicts durations from recorded runs; see rhylthyme://guide/tools.

NameTypeReqDescription
finishAtstring–ISO 8601 datetime everything must END at, e.g. '2026-11-26T18:00:00-05:00'. Start times are worked backwards from it.
historyarray–Recorded runs of this program (from load_run); adds predicted durations.
predictionContextobject–Optional: environmentId, userTags (variance factors), userId, programVersion, minIdentical, minModel, corrThreshold, verdicts. See rhylthyme://guide/tools.
programobjectyesProgram JSON; shape under validate_program.
program_idstring–Saved program UUID: loads the user's own recorded runs as the history.
startAtstring–ISO 8601 start datetime. Ignored with finishAt.
tokenstring–Access token from the login tool. Omit when the account is connected.
useDurationsstring–planned (default): analyse the program as authored. predicted: as the history says it will run.

calibrate_program ~218

Propose durations for a saved program from its recorded runs: median as the default, P10 to P90 as the range, never narrower than the author's, with the evidence per step and the effect on total length. Saves nothing: pass `accept` to get the calibrated program, then save_program. Needs the user's Rhylthyme account.

NameTypeReqDescription
accept––Step ids to accept, or "all": also returns the calibrated program. Nothing is saved either way.
historyarray–Run records to use instead of the stored ones.
kinteger–Measurements a step needs for a proposal (default 5).
programobject–Program JSON to calibrate; omit to use program_id's saved JSON.
program_idstring–Saved program UUID whose recorded runs are the evidence.
sincestring–Only runs started on or after this date (YYYY-MM-DD or ISO).
tokenstring–Access token from the login tool. Omit when the account is connected.

No output schema declared.

No examples provided.

create_environment ~93

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

import_from_source ~202

Import a recipe or protocol from a URL or service into a program. source: spoonacular, themealdb (recipes); protocolsio, opentrons, benchling (lab); cooklang (.cook URL). action: search (no login), import (query = URL or id), random. import, random and benchling need the account. `enrich: true` splits an import into parallel tracks. Then call visualize_schedule.

NameTypeReqDescription
actionstringyes–
enrichboolean–With action='import': split the import into parallel tracks with cross-track triggers. One model call, capped per day.
querystring–Keywords (search), or the URL or id (import).

No examples provided.

import_text ~210

Turn pasted text (a recipe, protocol, run sheet or training plan) into a validated multi-track program on the server, in four model turns, with a table of the source span each step came from. Use when the user pastes the steps and no URL importer fits. Needs the user's Rhylthyme account. Capped per day; you can instead author the program yourself and call validate_program.

NameTypeReqDescription
deadlinestring–When everything must be finished, if the user said: '18:00', 'dinner at six', an ISO datetime.
environmentTypestringyeskitchen, lab, events, gym or generic.

Common questions

What is the Rhylthyme MCP server?

Rhylthyme is an MCP server listed in the public MCP registry as com.rhylthyme/rhylthyme. Real-time multi-track schedules for cooking, lab protocols, events and workouts. Validate and share. This page covers its hosted endpoint (https://mcp.rhylthyme.com/mcp).

Is the Rhylthyme MCP server safe to use?

Rhylthyme scores 78 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Rhylthyme MCP server expose?

Rhylthyme exposes 19 tools: validate_program, analyze_schedule, visualize_schedule, import_from_source, import_text, and 14 more. Their descriptions and schemas cost roughly 2,441 tokens of context every time the server is loaded.

Does the Rhylthyme MCP server require authentication?

No. We connected to Rhylthyme without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Rhylthyme MCP server still maintained?

Rhylthyme is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
