Summary

Adds the M2M Sentinel Action Provider to @coinbase/agentkit (TypeScript) to equip autonomous AI agents with deterministic preflight smart contract bytecode capability inspection, proxy resolution, and market telemetry on Base Mainnet (chainId: 8453) in <35ms.

---

Key Capabilities

• Proxy Resolution: Resolves EIP-1967, UUPS, and Beacon proxy implementation slots before agents interact with unverified contracts.
• Bytecode Capability Checks: Inspects target contracts for pause/freeze controls, token mint selectors, and opcode traps.
• Base Gas & Price Telemetry: Median pool pricing across Base DEXes and priority gas suggestions.
• Deterministic EVM Truth: Pure bytecode observations with explicit unknown states (notASafetyGuarantee: true).

---

Actions Provided

1. audit_contract: Inspect target Base contract bytecode capability observations, proxy implementation slots, and limitations (address: string).
2. get_gas_metrics: Get real-time Base network gas execution metrics and priority fee recommendations.
3. get_token_price: Observe real-time Base DEX token prices for slippage checks and preflight valuation (symbol: string).
4. get_service_status: Check operational status and trust quorum of M2M Sentinel verification rails.

Test Plan

• Added Vitest unit tests in m2mSentinelActionProvider.test.ts covering network validation (Base mainnet 8453 and Base Sepolia 84532) and action execution mocks.
• Tested end-to-end against live Base Mainnet RPC and M2M Sentinel production gateway.

The M2M Sentinel MCP server path and clean-install checks are green, with the live Base evidence response preserving provenance and unresolved states. The contribution is ready for review and is not being represented as an official MCP integration. Could you confirm whether any changes or a different owner are needed? Thanks.
