## 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 2026-09-20.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 234 tokens (~46/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability check failed: schema churn in the 24 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 5 additions.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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.

## Install

### How do I install the ACEL Observatory MCP server?

ACEL Observatory is a hosted endpoint at https://radar.pccswart.co.za/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 mcpServers block is a cross-client convention. Remote transports vary, so check your client's docs.

## Common questions

### What is the ACEL Observatory MCP server?

ACEL Observatory is an MCP server listed in the public MCP registry as za.co.pccswart.radar/acel-demand-radar. Machine-readable entity discovery with provenance, trust and verified source evidence. This page covers its hosted endpoint (https://radar.pccswart.co.za/mcp/).

### Is the ACEL Observatory MCP server safe to use?

ACEL Observatory scores 61 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 ACEL Observatory MCP server expose?

ACEL Observatory exposes 5 tools: search_entities, get_entity, search_offerings, get_evidence, compare_entities. Their descriptions and schemas cost roughly 211 tokens of context every time the server is loaded.

### Does the ACEL Observatory MCP server require authentication?

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

### Is the ACEL Observatory MCP server still maintained?

ACEL Observatory is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
