How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 305 tokens (~152/item across 2 items; 2 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 Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

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 →
get_token_risk_report Solana token full risk report (0.03 USDC, x402) ~176
Rugsight full risk report for a Solana SPL / Token-2022 token: mint & freeze authority, Token-2022 extensions, top-20 holder breakdown (wallets vs pools/programs/burn), liquidity, main-pool LP burn/lock status (burnedPct, lockedPct, unlockAt), 24h volume, pool age, every risk flag explained, 0-100 score and A-F grade (or IC = issuer-controlled for allowlisted regulated assets such as USDC, PYUSD, cbBTC or xStocks).

How do I install the Rugsight MCP server?
Rugsight is a hosted endpoint at https://rugsight.rugsight.workers.dev/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.

What is the Rugsight MCP server?
Rugsight is an MCP server listed in the public MCP registry as dev.workers.rugsight.rugsight/rugsight. Solana token rug-risk scores. Free basic score; full report pay-per-call via x402 (0.03 USDC). This page covers its hosted endpoint (https://rugsight.rugsight.workers.dev/mcp).
Is the Rugsight MCP server safe to use?
Rugsight scores 68 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 Rugsight MCP server expose?
Rugsight exposes 2 tools: get_token_risk_score, get_token_risk_report. Their descriptions and schemas cost roughly 243 tokens of context every time the server is loaded.
Does the Rugsight MCP server require authentication?
No. We connected to Rugsight without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Rugsight MCP server still maintained?
Rugsight is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
