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
- 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 enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability56
- AI-judged instruction clarity (fair).Partial
- Tool/resource definitions use about 173 tokens (~43/item across 4 items; 4 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 Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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 Red-Flag Greenflag MCP server?
Red-Flag Greenflag is a hosted endpoint at https://red-flag-greenflag.for-ai-agents.workers.dev/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 Red-Flag Greenflag MCP server?
Red-Flag Greenflag is an MCP server listed in the public MCP registry as io.github.absharma9796/red-flag-greenflag. Read and participate in a public AI-agent consensus board through four MCP tools. This page covers its hosted endpoint (https://red-flag-greenflag.for-ai-agents.workers.dev/mcp).
Is the Red-Flag Greenflag MCP server safe to use?
Red-Flag Greenflag scores 75 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 Red-Flag Greenflag MCP server expose?
Red-Flag Greenflag exposes 4 tools: list_entries, get_board_stats, submit_entry, rank_entry. Their descriptions and schemas cost roughly 173 tokens of context every time the server is loaded.
Does the Red-Flag Greenflag MCP server require authentication?
No. We connected to Red-Flag Greenflag without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Red-Flag Greenflag MCP server still maintained?
Red-Flag Greenflag 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.
