MCP
Base MCP
Secure local transaction building with zero private key exposure. Every call is user-approved through Base Account web flows before it touches the network.
- Local intent construction
- Zero key exposure
- Scoped approvals
Agents + Base MCP + x402 = ♾️
Autonomous AI agent swarms on Base.
The infrastructure layer combining Base MCP for secure onchain execution and x402 for instant Machine-to-Machine (M2M) micro-economies.

Core architecture
A protocol stack built for machine economies.
Three composable layers turn isolated models into an accountable, self-funding onchain workforce.
x402
x402 Protocol
HTTP-native micropayments let agents autonomously purchase real-time data, compute and services — settled in USDC on Base within seconds.
- 402 Payment Required
- Sub-cent settlement
- Per-request metering
Swarm
Multi-Agent Swarms
Modular agents — Scout, Analyst, Executor — collaborate, cross-fund tasks and reach consensus in real time under a shared treasury policy.
- Role-based agents
- Cross-funding
- Consensus execution
How it works
The M2M loop, step by step.
Follow how Scout, Risk Officer, and Base MCP collaborate to turn a swarm instruction into a user-approved onchain action.
Step 01
Scout Agent
Purchases real-time data feeds using x402 micro-payments — mempool signals, vault APYs, and Aerodrome pool state — settled in USDC on Base.
- HTTP 402 Payment Required handshake
- Sub-cent USDC settlement (~$0.002)
- Feeds streamed into swarm shared memory
Swarm control
Live orchestration dashboard
Real x402 USDC payments into Scout, curated Morpho vaults on Base, and onchain deposit history for your wallet.

The pool charges the bite, not the volume.
A swarm is many small things. The hook measures each swap against the depth standing at the current price and charges it in proportion to the share it eats. It is the pool’s own arithmetic, read live, so the charge adapts to liquidity with nothing to tune and nobody to tune it.
Agent scale
A crumb pays nothing
A swap worth 5 basis points of the standing depth or less is not charged a reduced premium. It is not charged at all. Agent sized flow costs the pool fee and nothing more.
Concentration
A whole bite pays
One actor swallowing the depth takes the price with it and hands the liquidity behind it a worse position than the one it quoted. The premium rises with the share taken and stops dead at 3%.
Destination
Paid out in the same call
The premium is donated into the pool in the transaction that charges it, then the claim is burned. Between transactions the hook holds no ETH, no tokens and no claim. There is no pot to distribute.
What a swap would pay
against a 7 ETH model- Share of depth
- 0.29%
- Premium rate
- 0.01%
- You would pay
- 0.000002 ETH
This is 0.29% of the depth in one bite, so it pays 0.01% on top of the pool's own 0.30% — donated to the liquidity absorbing it, in the same transaction.
The constants
Compiled into the bytecode. There is no setter for any of them.

- Premium ceiling

- Free bite

Addresses
Nothing is deployed yet. The three addresses appear here at deployment, verified on Basescan before any liquidity exists.
