Works with Claude, with some setup first
You need a Valta key (create it on the maker’s site) · Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone
Let AI install it
Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.
Please install the MCP server Valta for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "valta": { "command": "npx", "args": [ "-y", "valta-mcp" ], "env": { "VALTA_API_KEY": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For VALTA_API_KEY, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the Valta tools really show up.This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.
Install Node.js (if you don’t have it)
Already installed? Check first · Open Terminal, type this command and press Enter
node -v- A version number such as v26.13.1 = installed, skip this step
- "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
How to open Terminal
Mac: press ⌘ + Space, type Terminal, press Enter
Windows: open Start, type Windows PowerShell, then Open
Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed
Open the Node.js download page ↗
When it’s done, close Terminal, open it again and run the same command. You should see a version number:

Common questions
Is Valta safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: VALTA_API_KEY
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed 4 months ago, and the latest version (0.1.2) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

valta-mcp
An MCP (Model Context Protocol) server for Valta — financial governance for AI agents. Exposes Valta's spend gate and audit trail as MCP tools, so any MCP-compatible client (Claude Desktop, Claude Code, Cursor, and others) can call them directly.
What this is — and isn't
This server is a thin wrapper over Valta's real, hosted REST API. It does not implement any spend logic, limits, or hashing itself — every tool call here is a pass-through to https://valta.co/api/v1/..., where the actual enforcement (spend gate, audit chain) happens. This repo is the protocol adapter, not the enforcement engine.
Important, read before relying on this for anything security-sensitive: most of these tools are advisory, not enforcing. A tool description telling a model "call this before spending" is guidance, not a guarantee. valta_request_spend, for example, only governs spend that routes through it — it does not intercept or prevent spending that happens through some other tool, API, or webhook the agent has independent access to.
One tool is different: `valta_proxy_request`. Instead of asking the model to check in before spending elsewhere, this one *is* the spend — the agent declares an outbound call's cost and routes the actual call through Valta, which checks it against wallet limits and only makes the real request (using your own stored credential) if approved. If it's blocked, the real provider is never contacted at all. This is a genuine, code-level guarantee, not an honor system — but only for the specific services Valta has wired up for proxying (currently: Stripe, Serper, Polygon). Any spend that happens through a channel other than this proxy — the agent's own separate API key, a webhook, a tool this server doesn't know about — is outside what any of these tools can see or stop. See Design notes below.
Install
npm install -g valta-mcpOr run directly without installing:
npx valta-mcpConfiguration
Get an API key at valta.co/dashboard → Settings → API Keys → Create key.
Add to your MCP client's config (e.g. Claude Desktop's claude_desktop_config.json):
{"mcpServers": { "valta": { "command": "npx", "args": ["valta-mcp"], "env": { "VALTA_API_KEY": "sk_valta_your_key_here" } } } }
Tools
| Tool | What it does |
|---|---|
valta_check_balance | Read an agent's wallet balance and limits |
valta_request_spend | Request authorization for a spend — approved or denied by the real spend gate |
valta_create_wallet | Create a new named wallet with optional spend limits |
valta_freeze_agent | Kill switch — freeze an agent's wallet, blocking further spend |
valta_unfreeze_agent | Resume a frozen agent's wallet |
valta_get_audit_trail | Read the hash-chained audit trail of spend decisions |
valta_list_wallets | List all named wallets on the account — use this to discover wallet names before checking balance/spending |
valta_transfer_funds | Transfer USDC directly between two of your agent wallets |
valta_list_agents | List all agents on the account |
valta_get_agent | Get details for a single agent |
valta_run_agent | Trigger an agent to run a task |
valta_get_agent_run | Check the status/result of a specific agent run |
valta_list_policies | List spending policies configured on the account |
valta_set_policy | Create a new spending policy (daily cap, per-transaction cap) |
valta_proxy_request | Make a real outbound call to a connected service (Stripe, Serper, Polygon) through Valta's spend-gated egress proxy — declares a cost up front, only reaches the real provider if approved, refunds automatically on failure |
valta_list_proxy_requests | List the receipts for every call the egress proxy has handled — allowed, blocked, refunded, or pending approval, and why |
Every tool's description in src/index.ts states plainly what it enforces and what it doesn't — read those before wiring this into anything that touches real money.
Design notes
Why there's no "non-bypassable system prompt." An earlier draft of this project considered shipping a system-prompt instruction block claiming to make spend gating "non-bypassable." That claim doesn't hold up, for two reasons:
- MCP servers don't control the host's system prompt. Claude Desktop, Claude Code, Cursor, and other hosts each own their own system prompt. An MCP server provides tools and, in some cases, a limited
instructionsfield — it cannot inject a binding, universally-enforced rule into the conversation. - A system prompt is a request to the model, not a code-level constraint. Even where a host does surface server instructions, an agent can still be prompt-injected, jailbroken, or simply routed through a different tool entirely that doesn't call this server at all. Claiming otherwise would be exactly the kind of gap this project exists to close — trusting the model to self-police is the failure mode Valta's spend gate was built to avoid in the first place.
What actually provides a guarantee, and what doesn't. There are now two different levels of enforcement in this server, and it matters which one a given tool gives you:
- Spend authorized by calling
valta_request_spendis genuinely checked against real limits, server-side — but only if the agent chooses to call it first. The gap is spend that happens through some *other* channel the agent has access to. - Spend routed through
valta_proxy_requestis checked *before the real call is made at all* — there's no step where the agent could skip the check and still have the payment go through, because the payment-triggering call and the check are the same action. That closes the gap described above, but only for the services this server has wired up for proxying (Stripe, Serper, Polygon as of this writing) — extending it to a new service means adding real credential-handling logic for that provider's specific auth scheme, not flipping a config flag.
If a use case needs a hard guarantee for a service not yet listed above, that service needs to be added to Valta's proxy gate first — open an issue or a PR.
