## 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**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (create_order).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 79/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1386 tokens (~86/item across 16 items; 12 tools + 4 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 87/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 60% 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 12 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 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.

## Common questions

### What is the GLOBALCELL eSIM MCP server?

GLOBALCELL eSIM is an MCP server listed in the public MCP registry as dev.globalcell/mcp. Travel eSIMs for 130+ countries: plan a trip, compare plans, buy, install and diagnose. This page covers its hosted endpoint (https://mcp.globalcell.dev).

### Is the GLOBALCELL eSIM MCP server safe to use?

GLOBALCELL eSIM scores 67 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 GLOBALCELL eSIM MCP server expose?

GLOBALCELL eSIM exposes 12 tools: search_destinations, list_plans, get_plan, recommend_plans, compare_plans, and 7 more. Their descriptions and schemas cost roughly 965 tokens of context every time the server is loaded.

### Does the GLOBALCELL eSIM MCP server require authentication?

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

### Is the GLOBALCELL eSIM MCP server still maintained?

GLOBALCELL eSIM 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.
