Endpoint Security80
Transport & Reachability100
Schema Quality & AI Usability70
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 2131 tokens (~177/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management22
  • Stability check failed: schema churn in the 26 days we've observed: 7 tool removals, 0 breaking changes, 0 auth/transport breaks, 8 additions. See how to fix → Fail
Tool Coverage99
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 97% of tool parameters carry a description.Partial
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "pay_decision_snapshot" implies "pay" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail

MCP tools · 12 exposed · ~2,108 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Install

How do I install the Straelo Relay MCP server?

Straelo Relay is a hosted endpoint at https://relay.straelo.com/mcp/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the Straelo Relay MCP server?

Straelo Relay is an MCP server listed in the public MCP registry as com.straelo/relay. MCP tools for agents: web research, content extraction, email, DNS, and blockchain intelligence. This page covers its hosted endpoint (https://relay.straelo.com/mcp/).

Is the Straelo Relay MCP server safe to use?

Straelo Relay scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Straelo Relay MCP server expose?

Straelo Relay exposes 12 tools: url_clean_content, email_validator_basic, web_intelligence, chain_contract_call, blockchain_intelligence, and 7 more. Their descriptions and schemas cost roughly 2,108 tokens of context every time the server is loaded.

Does the Straelo Relay MCP server require authentication?

No. We connected to Straelo Relay without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Straelo Relay MCP server still maintained?

Straelo Relay is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
