M2M Sentinel does not always answer

Over the last week it answered 50.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

This one needs environment variables set before it will start: M2M_SENTINEL_API_KEY (Optional M2M Sentinel API key for prepaid access.). The author declared them in the registry entry; get the values from the project itself.

This server publishes 1 more address. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

m2m

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.

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.

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.

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.

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.

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.

M2M Sentinel — questions

Answers built from our own checks of this server.

What can M2M Sentinel do?

It exposes 6 tools, read directly from the server on our last check. Among them: m2m_audit_contract, m2m_get_dex_liquidity, m2m_get_gas_metrics, m2m_get_service_status, m2m_get_token_price, m2m_get_whale_signals. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is M2M Sentinel working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 182 checks got a reply (50.0%), average response time 278 ms. The bar chart above shows every period we have measured.

How do I connect M2M Sentinel?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does M2M Sentinel need an API key?

No. M2M Sentinel completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is M2M Sentinel?

It answers our handshake in 278 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use M2M Sentinel?

The npm package @m2msentinel/sdk was installed 65 times in the last week. Week over week that is -61%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is M2M Sentinel open source?

Yes — it is published under the MIT licence, written in JavaScript and 2 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
