MCP Server for Z.AI - A Model Context Protocol server that provides AI capabilities
Nothing to run from here
Achromat MOM 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
Recall and calibrate policy-compliant tool-call arguments before execution. Does not run the tool.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user achromat-mom-mcp '--' npx -y @achromat-ai/mcp-server
# 2 — ask your agent for something these tools do
# achromat_recall, achromat_calibrate, achromat_register_identity
Achromat MOM 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. This one can run either way — at an address its publisher runs, or as a process under your own user, with your files and your network — and this marketplace is in the path of neither.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user achromat-mom-mcp '--' npx -y @achromat-ai/mcp-serverReconnect, or start a new session, and the tools appear in the model’s tool list.
Or connect to its publisher’s address
Its publisher also runs it at https://achromat.ai/mcp: nothing to start on your machine, and this marketplace is not in the path.
claude mcp add --scope user --transport http achromat-mom-mcp https://achromat.ai/mcpFree on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it asks of you
Nothing is required, but it can take ACHROMAT_AGENT_KEY_FILE (Path of the agent's Ed25519 private key (unencrypted PKCS#8 PEM). Created on first use if the file does not exist.), ACHROMAT_BASE_URL (Service origin. Must be https (plain http is accepted only for localhost).), ACHROMAT_REF (Optional attribution tag (1 to 32 characters from a-z, 0-9, _ and -) sent as ?ref= on the registration calls only. An invalid tag is ignored.) if you want to set them.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
3 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.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Call this BEFORE you run a tool that policy might block (payments, credit decisions, robot or plant commands, shell, SQL, web requests). It asks Achromat MOM whether a verified compliant version of this call already exists. Pass the arguments you intend to send: the names of their keys (not the…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The area the tool call belongs to. |
| tool_name | string | yes | The exact name of the tool you are about to call, for example dispatch_wire. |
| task_description | string | yes | — |
| arguments | object | yes | — |
Use this when achromat_recall found nothing, or when the stakes are high. It evaluates your candidate tool call against live policy and returns a verdict. BLOCK comes with a steering_directive and a trap_id: change the arguments as the directive says, then call this tool again with the same…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The area the tool call belongs to. |
| tool_name | string | yes | The exact name of the tool you are about to call, for example dispatch_wire. |
| task_description | string | yes | — |
| arguments | object | yes | The arguments of the tool call you want checked. A non-empty JSON object. Never put secrets or credentials in it. |
| trap_id | string | no | Only on a retry: the trap_id the earlier BLOCK answer gave you. Send the corrected arguments with it. |
Achromat needs a private key on this machine before it can answer anything, and none exists yet. This tool creates one: it generates an Ed25519 key pair, completes a short proof of work (about a second), registers the public key with Achromat MOM, and saves the private key to a file that only this…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| user_confirmed | boolean | yes | Set to true ONLY after the user has said yes to creating an identity. If they have not been asked, ask first and do not call this tool. |

Release 0.1.4 · scanned 5 Nov 2026
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.

Implementation sourceread
Package metadataread
Live transportnot available
Tools were statically extracted from the published source (3 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. moderate is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| achromat_recall | external-sink | external-sink: declares readOnlyHint: false, openWorldHint: true, handler sends an HTTP POST ( client.post("/api/v1/recall") at dist/tools.js:72 |
| achromat_calibrate | external-sink | external-sink: declares readOnlyHint: false, openWorldHint: true, handler sends an HTTP POST ( client.post("/api/v1/calibrate") at dist/tools.js:75 |
| achromat_register_identity | external-sink | external-sink: declares readOnlyHint: false, openWorldHint: true |
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.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.1.4. Pin a release below and the command asks for exactly that one.

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 Achromat MOM 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.
