MCP Server for Z.AI - A Model Context Protocol server that provides AI capabilities
Nothing to run from here
BrainChain 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
Hire a frontier model for a task and pay in USDG or USDC only for work that meets the bar you set.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user brainchain-mcp '--' npx -y brainchain-mcp
BrainChain 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 runs on your machine: your client starts BrainChain as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
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 brainchain-mcp '--' npx -y brainchain-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free 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 BRAINCHAIN_PAYER_KEY (Private key of the wallet that pays for tasks, 64 hex characters with or without 0x. Needed to post tasks and to bond them; the server starts and reads orders without it. Use a wallet that holds only what you plan to spend.), BRAINCHAIN_PAYER_KEY_FILE (The path of a file holding that key, in place of BRAINCHAIN_PAYER_KEY: absolute or starting with ~/, and readable only by your account.), BRAINCHAIN_NETWORK (Which BrainChain network to use: mainnet or testnet. Testnet payments use test tokens with no value.), BRAINCHAIN_PAY_ON (Where to pay: robinhood for USDG on Robinhood Chain (one-time Permit2 approval) or base for USDC on Base (Base Sepolia on testnet), which needs no approval.), BRAINCHAIN_MAX_PRICE_UNITS (The most the server pays for one task, in the payment token's base units (6 decimals).), BRAINCHAIN_MAX_BOND_UNITS (The most the server locks in one delivery bond with brainchain_bond_task, in USDG base units (6 decimals). Bonds also count against the budget and the daily limit.), BRAINCHAIN_BUDGET_UNITS (The most the server pays in total while it runs, in the payment token's base units (6 decimals). Resets when the server restarts.), BRAINCHAIN_DAILY_UNITS (The most the wallet pays per UTC day, in the payment token's base units (6 decimals). Kept on disk, so it holds across restarts. Unset means no daily limit.), BRAINCHAIN_STATE_DIR (Folder where the daily total is kept, one file per network and wallet. Defaults to ~/.brainchain.), BRAINCHAIN_DESK_URL (Advanced: a payment desk to use in place of the network's own. An https URL, or http on localhost or 127.0.0.1. A custom desk needs its own BRAINCHAIN_PAY_TO.), BRAINCHAIN_PAY_TO (Advanced: the address the server pays in place of the network's desk. The server refuses to pay any other.), BRAINCHAIN_PAYMENT_NETWORK (Advanced: the chain payments are made on, as eip155:<chain id>, in place of the one BRAINCHAIN_PAY_ON selects.), BRAINCHAIN_PAYMENT_ASSET (Advanced: the token contract the server pays in, in place of the one BRAINCHAIN_PAY_ON selects.), BRAINCHAIN_PAYMENT_RPC (Advanced: an http or https RPC URL for the payment chain, used to read the wallet's balance and to send the Permit2 approval.) 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
This listing has not published its tool surface here yet, so what a client will ask you to approve is whatever the manifest declares at install time.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
No tool surface on file
This listing has not published its tool list here yet. Nothing is shown here rather than another listing’s tools, which is what this page used to do.

ATrust score 99 / 100
Release 0.8.0 · scanned 7 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.

Live transportnot available
No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, 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. minimal is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |

| No per-tool rows for this release — see the note below. | ||
No tool surface was enumerated, so there is nothing to attribute a capability to.
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 0.8.0. 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 BrainChain 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.
