MCP server that wraps the Dagster GraphQL API — manage runs, assets, schedules, sensors, and backfills from any MCP client
Nothing to run from here
Fittest is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Three ML interatomic potentials check a molecule: trust (Beta-posterior score, 90% CI) or DFT.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http fittest-mcp https://fittest-mcp.westus2.cloudapp.azure.com/mcp
# 2 — ask your agent for something these tools do
# check_structures, explain, swarm_status and 1 more
Fittest costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http fittest-mcp https://fittest-mcp.westus2.cloudapp.azure.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
4 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Ask the Fittest swarm whether a machine-learned interatomic potential can be trusted on your molecular structures, or whether they need DFT. Three model agents (MACE-MPA-0, AIMNet2, Orb-v3) predict forces; their disagreement sigma_F and the Calibrator's DFT-label ledger give the verdict. Input structures: XYZ text (single or multi-frame; bare 'El x y z' atoms on separate lines or separated by c
| Parameter | Type | Required | Notes |
|---|---|---|---|
| structures | yes | — | |
| include_forces | boolean | no | — |
Explain why Fittest trusted or escalated ONE structure (XYZ text or {Z|symbols, R}): the verdict rule applied, sigma_F vs tau, the Calibrator bucket with its label count, the posterior P(correct) of every candidate in it, which model agents disagree most, and the most uncertain atoms.

Show the Fittest population: model agents (answerers) and the Skeptic (critic) with reputations from the ledger, the calibration domain, tau and the verdict rule, which models are live, and the evolution family trees if published. Logging: every call to this server is logged (UTC time, tool name, an anonymous client id = salted hash of client name + IP), structure and atom counts, verdict counts,
No parameter schema on file.
Aggregate usage of this server: distinct users (anonymous clients that got at least one structure verdict; internal test clients excluded), total calls, calls per tool, first/last call time. No per-user data. Logging: every call to this server is logged (UTC time, tool name, an anonymous client id = salted hash of client name + IP), structure and atom counts, verdict counts, latency and ok/error

ATool-list grade · score 96 / 100
Release 0.1.1 · scanned 1 Nov 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Fittest can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
