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.

Security

Grade A, and why

seoradar-mcp 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 11d 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.

What it actually says

CLAUDE.md — seoradar-mcp

MCP server for SEO Radar: SEO audits and URL monitoring via the seoradar.cz REST API.

src/ layout

src/
  config.ts          — env var parsing (SEORADAR_API_KEY, SEORADAR_API_URL)
  client.ts          — SeoRadarClient: all HTTP calls + error mapping
  format.ts          — response formatters (audit summary, monitor data, etc.)
  index.ts           — McpServer bootstrap; wires all tools
  tools/
    seo-audit.ts
    get-audit-results.ts
    check-api-usage.ts
    list-monitored-urls.ts
    add-monitored-url.ts
    get-monitoring-status.ts
    remove-monitored-url.ts

Adding a tool

  1. Create src/tools/<tool-name>.ts exporting register(server: McpServer, client: SeoRadarClient): void.
  2. Add Zod input schema, call the appropriate client method, return formatted text.
  3. Import and call register(server, client) in src/index.ts.

Commands

npm test          # vitest unit tests
npm run lint      # eslint src/
npm run build     # tsc → dist/

API contract

All endpoints are documented in the OpenAPI spec at https://seoradar.cz/openapi.yaml. The SeoRadarClient in src/client.ts is the single place to add new API calls.

Changes

What this file has done since we first saw it

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.
