Category Search and Retrieval
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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability67
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 2259 tokens (~47/item across 48 items; 48 tools + 0 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 Coverage70
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 10% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "intelligence_execute_package" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
- An AI judge read all 49 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
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 12 Oct 26 0
- Stability: 0.97 → pass security

No change was recorded against any check on this day. Stability & Change Management went from 77 to 97. That category is still filling its 30-day observation window: 23 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 73 to 77. That category is still filling its 30-day observation window: 22 days of observed history at the previous scan, 23 at this one. The score rises as the window fills, whether or not the server changes.

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

How do I install the AI Arena Agent Tools MCP server?
AI Arena Agent Tools is a hosted endpoint at https://mcp.ai-arena.ca/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.

What is the AI Arena Agent Tools MCP server?
AI Arena Agent Tools is an MCP server listed in the public MCP registry as ca.ai-arena/agent-tools. Read-only US public-data screening tools with free Basic and Evidence tiers. This page covers its hosted endpoint (https://mcp.ai-arena.ca/mcp).
Is the AI Arena Agent Tools MCP server safe to use?
AI Arena Agent Tools scores 82 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 AI Arena Agent Tools MCP server expose?
AI Arena Agent Tools exposes 48 tools: ai_arena_status, sec_recent_filings_basic, sec_recent_filings_evidence, sec_action_radar_basic, sec_action_radar_evidence, and 43 more. Their descriptions and schemas cost roughly 2,204 tokens of context every time the server is loaded.
Does the AI Arena Agent Tools MCP server require authentication?
No. We connected to AI Arena Agent Tools without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the AI Arena Agent Tools MCP server still maintained?
AI Arena Agent Tools 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.
