Available components
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 Security54
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 36 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability82
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 3124 tokens (~86/item across 36 items; 36 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 36 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 36 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
How do I install the WebLens MCP server?
WebLens is a hosted endpoint at https://api.weblens.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.

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 →
answer_question ~76

preview_endpoint ~149
FREE. See what a paid WebLens endpoint costs and what it returns before paying: the live price, a one-line summary, and a recorded sample of the exact response shape. Endpoints with no paid upstream (/fetch/basic, /contents, /map) also run a real truncated LIVE preview when you pass a url; SerpAPI- and Anthropic-backed endpoints return the recorded sample only, because free live runs there would burn upstream credits.

Gives weighted risk signals and an A-F grade. Reads NOTHING on-chain — pair it with a contract/liquidity checker. Price: $0.05
| Name | Type | Req | Description |
|---|---|---|---|
| chain | string | – | Optional chain label, e.g. base, ethereum, solana |

What is the WebLens MCP server?
WebLens is an MCP server listed in the public MCP registry as dev.weblens/weblens. Scrape, crawl, map and extract the web. Pay per call in USDC, no account or API key. This page covers its hosted endpoint (https://api.weblens.dev/mcp).
Is the WebLens MCP server safe to use?
WebLens scores 77 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 WebLens MCP server expose?
WebLens exposes 36 tools: preview_endpoint, fetch_webpage, fetch_webpage_pro, screenshot, search_web, and 31 more. Their descriptions and schemas cost roughly 3,124 tokens of context every time the server is loaded.
Does the WebLens MCP server require authentication?
No. We connected to WebLens without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the WebLens MCP server still maintained?
WebLens is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
