## 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 2026-10-02.

- **Endpoint Security**: 46/100
  - 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 7 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 check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 40/100
  - Verified sse transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 29/100
  - AI-judged instruction clarity (poor).
  - Tool/resource definitions use about 746 tokens (~106/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - Manipulation check failed: an AI judge found 1 of 8 captured unit(s) of tool text manipulative, the first being "server instructions".
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Common questions

### What is the Blue Synergy Cortex MCP server?

Blue Synergy Cortex is an MCP server listed in the public MCP registry as io.github.novotapeter-bs/cortex. Long-term, drift-free cognitive memory engine for AI Agents and Cursor IDE. This page covers its hosted endpoint (https://cortex.bluesynergy.io/v1/mcp/sse).

### Is the Blue Synergy Cortex MCP server safe to use?

Blue Synergy Cortex scores 46 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 Blue Synergy Cortex MCP server expose?

Blue Synergy Cortex exposes 7 tools: cortex_recall, cortex_get_project_spec, cortex_store_memory, cortex_triage_general, cortex_manage_draft, and 2 more. Their descriptions and schemas cost roughly 534 tokens of context every time the server is loaded.

### Does the Blue Synergy Cortex MCP server require authentication?

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

### Is the Blue Synergy Cortex MCP server still maintained?

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