Straelo Relay missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 8

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

blockchain

blockchain_intelligence

Inspect exactly one Base or Ethereum transaction, address, or contract with bounded read-only RPC calls and return deterministic context, observed signals, evidence, coverage, and actionable follow-up.

chain

chain_contract_call

Execute a read-only EVM smart contract call on Ethereum or Base and return the normalized result without managing an RPC provider.

defi

defi_execution_snapshot

Compare read-only Base swap quotes from 1inch and KyberSwap, returning normalized comparable output, consensus, dispersion, quote evidence, and explicit provider limitations without executing a swap.

domain

domain_intelligence

Inspect consolidated domain health in one machine-to-machine call: DNS, HTTP, HTTPS, TLS, redirects, MX, SPF, DMARC, email posture, observed security posture, and agent readiness. Returns structured issues, evidence, actions, and stateless changes.

email_validator_basic

Validate email syntax, domain and MX records for basic automated checks without SMTP mailbox verification.

pay

pay_decision_snapshot

Compare one supplied x402 v2 exact Base USDC payment requirement against declared intent and return deterministic consistency, mismatch, change, fingerprint, and coverage evidence without executing a payment.

url

url_clean_content

Extract clean readable webpage text from a public URL, removing boilerplate for LLM-ready research or RAG ingestion.

web

web_intelligence

Search, read, extract, verify with evidence, research, compare or detect web changes in one paid machine-to-machine product without orchestrating multiple web APIs.

Straelo Relay — questions

Answers built from our own checks of this server.

What can Straelo Relay do?

It exposes 8 tools, read directly from the server on our last check. Among them: blockchain_intelligence, chain_contract_call, defi_execution_snapshot, domain_intelligence, email_validator_basic, pay_decision_snapshot and 2 more. 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 Straelo Relay working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 600 ms. The bar chart above shows every period we have measured.

Did Straelo Relay ever remove tools?

Yes. dns_intelligence, domain_health, research_answer, search_evidence and 3 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect Straelo Relay?

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 Straelo Relay need an API key?

No. Straelo Relay completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Straelo Relay?

It answers our handshake in 600 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
