What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • run_flint_scout

    Use this tool to scan an intended agent transaction before execution. Two ways to pay for a scan. Credits first: buy credits once with scout_credits_topup (one $1.00 x402 payment for 100 scans), then call this tool with the same session_token and no payment_signature; FLINT draws

  • issue_authorization_record

    Use this tool before an AI agent initiates a payment, paid API call, checkout action, stablecoin transfer, x402 request, or delegated commercial transaction. It verifies agent authority, checks scope, issues a signed verification record, and returns evidence for dispute review an

  • verify_agent_authority

    Use this tool when a merchant or API seller receives a signed verification record from an agent. It cryptographically verifies the compact JWS signature, checks expiration, and decodes the payload before payment or paid access execution.

  • lookup_agent_reputation

    Use this tool to query the FLINT Trust Graph for a partner-scoped agent's historical reputation before permitting a payment, paid API call, checkout action, x402 request, or delegated commercial transaction. It returns aggregate reputation without exposing raw runtime identifiers

  • create_flint_trust_manifest

    Use this tool when a merchant, API seller, MCP tool provider, x402 endpoint, or agent storefront needs a `/.well-known/flint.json` Trust Manifest. It generates a machine-readable policy file declaring that autonomous economic actors must use FLINT authority verification, signed r

  • generate_authorization_scope

    Use this tool when an agent commerce workflow needs a well-formed delegated authorization scope before issuing a signed verification record. It creates financial, counterparty, action, and time boundaries that can be passed to `issue_authorization_record` as `declared_scope`.

  • validate_agent_commerce_readiness

    Use this tool when reviewing a commerce architecture, API marketplace, paid MCP tool, x402 endpoint, or autonomous checkout flow. It checks whether the design uses FLINT as the transaction-time authority layer before execution, verifies signed records, submits outcomes, publishes

  • issue_agent_passport

    Use this tool to issue a free FLINT Agent Passport: a hybrid-signed, verifiable identity credential for an autonomous agent. Before calling it, ask the principal for the accountable controller_id and controller_type, allowed actions, maximum transaction amount, and wallet address

  • get_agent_passport

    Use this tool to resolve a public FLINT Agent Passport by passport_id. It returns compact identity, mandate, status, ownership, and the public passport URL without echoing the full signed envelope. session_token is optional and not required to read a passport; the lookup itself i

  • update_agent_mandate

    Use this tool to update mutable mandate config for an existing FLINT Agent Passport. This updates allowed actions, amount limits, or notes only. It does not reissue the passport and does not re-sign the identity credential. If the passport is owned (claimed), pass session_token f

  • auth_request_otp

    Use this tool first in the agent-native authenticate-then-mint flow. It asks FLINT to email a one-time sign-in code to the given inbox address. Read the code from that inbox, then call auth_verify_otp with the same email and the code. Authenticating first means the passport you m

  • auth_verify_otp

    Use this tool right after auth_request_otp, with the code from the inbox. On success it returns session_token. Store that value and pass it as session_token on later calls, including issue_agent_passport, get_agent_passport, update_agent_mandate, claim_agent_passport, and refresh

  • claim_agent_passport

    Use this tool to attach an anonymously minted, unclaimed FLINT Agent Passport to an authenticated FLINT account. Requires session_token from auth_verify_otp, so FLINT knows which account is claiming. Pass claim_token from the mint's claim_url, or omit it when this same session al

  • refresh_claim_token

    Use this tool when a claim link is lost, expired, or was already consumed for a passport that is still unclaimed. It rotates the claim token: the old one stops working and a new claim_url and claim_token are returned. This is the fix for a lost or consumed claim token; do not rem

  • scout_credits_topup

    Call once with session_token to get a pay_url; pay it with awal (`awal x402 pay -X POST -d '{}' `) or any x402 client; no headers needed on the pay request. Or pass payment_signature to settle through this tool. One $1.00 x402 payment buys 100 FLINT Scout scan credits, matching t

  • scout_credits_balance

    Use this tool to check a signed-in account's FLINT Scout credit balance and recent ledger activity (topups, debits, refunds). Requires session_token from auth_verify_otp.

  • report_scout_outcome

    Use this tool after a run_flint_scout scan to report what actually happened: whether the scanned transaction was executed, held, cancelled, or executed despite a BLOCK verdict. FLINT cannot stop a wallet from transacting; this is the enforce-or-attest half of the contract. Author

Common questions

Is Agent Transaction Control safe?

It passed 4 of 4 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 5 months ago, 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 Business and above.

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:

  1. The FLINT remote connector — a hosted MCP server at https://flint.network/mcp that exposes FLINT's agent-verification tools. Nothing to run locally, no account required to start.
  2. 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.

  1. Issue a passport for the agent — issue_agent_passport. Free, hybrid-signed, returns a public verifiable URL. Agent name or id is enough.
  2. Authorize the intended action before any spend — issue_authorization_record. Binds the agent to a scope (what, how much, to whom).
  3. Verify at the moment of execution — verify_agent_authority. Returns a four-state verdict: allow, step-up, review, or block.
  4. 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:

ToolPurpose
issue_agent_passportIssue a free, hybrid-signed passport for an agent; returns a public verifiable URL.
get_agent_passportFetch an existing passport and its current state.
create_flint_trust_manifestProduce a portable trust manifest for an agent.
generate_authorization_scopeBuild a scope describing what an agent is permitted to do.
issue_authorization_recordBind an agent to an authorization before a spend.
update_agent_mandateUpdate the standing mandate that governs an agent's authority.
verify_agent_authorityVerify authority and integrity at transaction time; returns the four-state verdict.
lookup_agent_reputationCheck an agent's cross-merchant reputation before a higher-risk deal.
submit_transaction_outcomeRecord the outcome after completion, dispute, or review.
validate_agent_commerce_readinessScore 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.

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.
