## 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 2026-09-22.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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**: 87/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2507 tokens (~113/item across 22 items; 21 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 49/100
  - Stability check failed: schema churn in the 16 days we've observed: 0 tool removals, 1 breaking changes, 0 auth/transport breaks, 6 additions.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 21 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 23 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Common questions

### What is the 2b2t Atlas MCP server?

2b2t Atlas is an MCP server listed in the public MCP registry as io.github.bobymicjohn/2b2t-atlas. Search 2b2t locations, groups, highways, renders, Archive warps, and WDL metadata. This page covers its hosted endpoint (https://api.blackportal.cloud/mcp).

### Is the 2b2t Atlas MCP server safe to use?

2b2t Atlas scores 83 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 2b2t Atlas MCP server expose?

2b2t Atlas exposes 21 tools: get_location, get_warps, get_render_metadata, get_highway, get_world_downloads, and 16 more. Their descriptions and schemas cost roughly 2,425 tokens of context every time the server is loaded.

### Does the 2b2t Atlas MCP server require authentication?

No. We connected to 2b2t Atlas without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the 2b2t Atlas MCP server still maintained?

2b2t Atlas is still listed as active in the MCP registry. We last reached this channel on 22 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
