Authorization (16 Sept 2026). See the changelog before you install this server.
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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (arif_memory). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (fair).Partial
- Tool/resource definitions use about 3387 tokens (~78/item across 43 items; 8 tools + 35 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage73
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 19% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the arifOS — Constitutional AI Kernel MCP server?
arifOS — Constitutional AI Kernel is a hosted endpoint at https://arifos.arif-fazil.com/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 per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

What is the arifOS — Constitutional AI Kernel MCP server?
arifOS — Constitutional AI Kernel is an MCP server listed in the public MCP registry as io.github.ariffazil/arifos. Constitutional AI kernel with 13 MCP tools, 888_JUDGE verdict pipeline, and VAULT999 ledger. This page covers its hosted endpoint (https://arifos.arif-fazil.com/mcp).
Is the arifOS — Constitutional AI Kernel MCP server safe to use?
arifOS — Constitutional AI Kernel scores 78 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 arifOS — Constitutional AI Kernel MCP server expose?
arifOS — Constitutional AI Kernel exposes 8 tools: arif_init, arif_observe, arif_think, arif_route, arif_memory, and 3 more. Their descriptions and schemas cost roughly 1,371 tokens of context every time the server is loaded.
Does the arifOS — Constitutional AI Kernel MCP server require authentication?
No. We connected to arifOS — Constitutional AI Kernel without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the arifOS — Constitutional AI Kernel MCP server still maintained?
arifOS — Constitutional AI Kernel is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
