## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 374 tokens (~93/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 80/100
  - Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `phone_lookup` (~118 tokens)

Check phone carrier and line type

Check a user-provided phone number for carrier and line type. Optional US/CA caller-name data is a carrier listing, not identity verification. Uses existing account credits: 1 for landline/VoIP/toll-free, 3 for mobile or unknown; caller name adds 2. Reserves up to 5 credits before execution. Does not place calls or send messages.

Input parameters:

- `caller_name` (boolean): Request caller-name data; adds 2 credits.
- `number` (string, required): Phone number, preferably E.164 international format.

### `email_verify` (~65 tokens)

Check email syntax and domain

Check an email address supplied by the user for syntax, MX records, disposable-domain and role-address indicators. Does not prove mailbox ownership or guarantee delivery. Uses 1 existing account credit for a successful check; does not send email.

Input parameters:

- `email` (string, required): Email address to check.

### `ip_lookup` (~67 tokens)

Check IP location and network

Look up approximate IP location and network/provider indicators for an IP address supplied by the user. IP location is not a person's precise location or identity; privacy flags may be unavailable. Uses 1 existing account credit for a successful check.

Input parameters:

- `ip` (string, required): IPv4 or IPv6 address.

### `dns_check` (~85 tokens)

Inspect email DNS records

Inspect a user-provided domain's MX, SPF, DMARC or DKIM record and report issues. Does not change DNS. DKIM requires a selector. Uses 1 existing account credit for a successful check.

Input parameters:

- `check` (string, required)
- `domain` (string, required): Domain to check.
- `selector` (string): DKIM selector; required when check is dkim.

## Common questions

### What is the LookupLab MCP server?

LookupLab is an MCP server listed in the public MCP registry as io.github.PpiNeaPpLe/lookuplab. Phone carrier, email domain, IP network and DNS checks using your LookupLab account. This page covers its hosted endpoint (https://lookuplab.io/api/mcp).

### Is the LookupLab MCP server safe to use?

LookupLab scores 81 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 LookupLab MCP server expose?

LookupLab exposes 4 tools: phone_lookup, email_verify, ip_lookup, dns_check. Their descriptions and schemas cost roughly 335 tokens of context every time the server is loaded.

### Does the LookupLab MCP server require authentication?

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

### Is the LookupLab MCP server still maintained?

LookupLab 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.

### What did VerifyMCP test on the LookupLab MCP server?

VerifyMCP ran 13 checks on LookupLab, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
