What is risken-mcp-server CLAUDE.md?

Development instructions for RISKEN MCP Server, a Go server that connects coding assistants to RISKEN security APIs. RISKEN is used to manage security findings, alerts, and project access.

Use them when developing or operating this server with Docker, HTTP or standard input/output modes, OAuth, health checks, project queries, or Go tests.

They give developers the commands and configuration needed to build, run, authenticate, inspect, and test the server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01322	$0.01322
Opus 5	$0.00661	$0.00661
Sonnet 5	$0.00264	$0.00264
Haiku 4.5	$0.00132	$0.00132

Security

Grade A, and why

risken-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
