What this MCP does

Provides Base blockchain contract capability observations, proxy resolution, gas metrics, DEX liquidity, token prices, whale transfers, and service status.

Capabilities

Tools

6 tools
m2m_audit_contract
Inspect static bytecode capabilities (e.g. mint, pause, freeze, upgradeability slots), common proxy target resolution, and coverage index for a single Base contract address. Factual capability observation only, not a safety or exploitability guarantee. Distinguishable from m2m_get_service_status (infrastructure status) and legacy score-only endpoints.
Read only Open world Idempotent
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['address'], 'properties': {'address': {'type': 'string', 'pattern': '^0x[0-9a-fA-F]{40}$'}}, 'additionalProperties': False}
m2m_get_dex_liquidity
Fetch aggregate pool reserve, depth, and volume metrics across tracked Base DEX liquidity pools. Reports tracked-pool metrics only and does not filter by individual trading pair; contrast with m2m_get_token_price, which observes token spot prices.
Read only Open world Idempotent
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'properties': {}, 'additionalProperties': False}
m2m_get_gas_metrics
Fetch current Base gas price in wei/gwei with RPC provenance for the upstream observation. Read-only telemetry; does not inspect contract code, return token/DEX pricing, or authorize or submit transactions.

Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'properties': {}, 'additionalProperties': False}
m2m_get_service_status
Fetch operational status, upstream Base RPC quorum status, and persistence availability for M2M Sentinel infrastructure. Does not return blockchain or market telemetry.
Read only Open world Idempotent
Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'properties': {}, 'additionalProperties': False}
m2m_get_token_price
Fetch the median Base DEX spot price in USD across up to five deepest indexed pools, with contract address, decimals, and pool provenance for one allowlisted token symbol (e.g. USDC, WETH, AERO). Does not return historical price series; contrast with m2m_get_dex_liquidity, which returns aggregate pool reserve depth rather than an asset price.

Input schema 
{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'required': ['symbol'], 'properties': {'symbol': {'type': 'string', 'pattern': '^[A-Za-z0-9_-]{1,20}$'}}, 'additionalProperties': False}
m2m_get_whale_signals
Fetch up to 50 tracked recent high-value ERC-20 transfer signals on Base with transaction hashes, token/sender/receiver addresses, amounts, and valuation provenance. Observes large on-chain transfer events without query parameter limits; does not inspect contract bytecode or query DEX pricing.
