Common questions
Is Agent Transaction Control safe?
It passed 1 of 1 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

FLINT Cross-Domain Agent Passport
Know Your Agent at transaction time. Verify an AI agent's integrity and authority with FLINT before it moves money, and keep a signed record of what was checked.
What this is
This repository is the FLINT plugin for Claude Code and Cowork. It bundles two things:
- The FLINT remote connector — a hosted MCP server at
https://flint.network/mcpthat exposes FLINT's agent-verification tools. Nothing to run locally, no account required to start. - The `verify-agent-integrity` skill — a guided workflow that runs the verify-before-pay loop for you, so the assistant confirms an agent is authorized and uncompromised before it spends.
FLINT is the neutral verification network for AI agents that transact. It does not issue agents and it does not move money. It verifies, at the moment value moves, that the specific agent asking to pay is the one it claims to be, is still inside the authority it was granted, and has not been taken over. Every check returns a clear verdict and a signed record the counterparty keeps as evidence.
Why it exists
AI agents are being handed spending authority across stablecoin and card rails. The fraud and identity stack was built for humans: a device, a session, an account the institution itself issued and could watch. An agent transacting directly against an API has none of that, and the counterparty it transacts with did not issue it. Proving the human is real does not tell you the agent acting for them right now is authorized and uncompromised. That is the layer FLINT verifies.
Install
As a plugin (Claude Code or Cowork):
/plugin marketplace add thefraudfather/flint-plugin/plugin install flint@flint-network
This installs both the remote connector and the verify-agent-integrity skill.
Connector only (any MCP-compatible client):
Point your client at the FLINT remote server. The connection is a single entry:
{"mcpServers": { "flint": { "type": "streamable-http", "url": "https://flint.network/mcp" } } }
Or connect from flint.network/connect.
The verify-before-pay loop
The skill runs this loop; you can also call the tools directly.
- Issue a passport for the agent —
issue_agent_passport. Free, hybrid-signed, returns a public verifiable URL. Agent name or id is enough. - Authorize the intended action before any spend —
issue_authorization_record. Binds the agent to a scope (what, how much, to whom). - Verify at the moment of execution —
verify_agent_authority. Returns a four-state verdict: allow, step-up, review, or block. - Record the result after completion, dispute, or review —
submit_transaction_outcome. Feeds the cross-merchant reputation signal and leaves a retained record.
Tools
The connector exposes ten tools:
| Tool | Purpose |
|---|---|
issue_agent_passport | Issue a free, hybrid-signed passport for an agent; returns a public verifiable URL. |
get_agent_passport | Fetch an existing passport and its current state. |
create_flint_trust_manifest | Produce a portable trust manifest for an agent. |
generate_authorization_scope | Build a scope describing what an agent is permitted to do. |
issue_authorization_record | Bind an agent to an authorization before a spend. |
update_agent_mandate | Update the standing mandate that governs an agent's authority. |
verify_agent_authority | Verify authority and integrity at transaction time; returns the four-state verdict. |
lookup_agent_reputation | Check an agent's cross-merchant reputation before a higher-risk deal. |
submit_transaction_outcome | Record the outcome after completion, dispute, or review. |
validate_agent_commerce_readiness | Score how ready an agent or flow is to transact. |
How verification works
At the transaction handshake, FLINT runs six locked verification layers:
Principal Identity (the human or organization the agent acts for), Agent Identity (the specific agent it claims to be), Wallet Provenance (the funding source is what it should be), Authorization Scope (the action falls inside the authority granted), Environment Identity (the agent is running where its history says it runs), and Cross-Merchant Reputation (how the agent has behaved across the network).
Each verification returns one of four verdicts — allow, step-up, review, block — and a signed verification record. Records are hybrid-signed with both a classical and a post-quantum signature, so the evidence holds as cryptography evolves.

About
FLINT is built by KillChain, Inc. (d/b/a FLINT Network). FLINT is rail-agnostic and neutral by design: it verifies the agent so identity providers can keep proving the human and the rails can keep moving the money.
