Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02460 | $0.02460 |
| Opus 5 | $0.01230 | $0.01230 |
| Sonnet 5 | $0.00492 | $0.00492 |
| Haiku 4.5 | $0.00246 | $0.00246 |
Grade A, and why
servarr-mcp AGENTS.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 3d 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.

How it starts
The opening of the file, as written. The whole thing — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
servarr-mcp
MCP server for the Servarr stack (Sonarr, Radarr, Lidarr, Readarr, Prowlarr), packaged as a Docker container.
Status
Single source of truth: STATUS.md. Do not duplicate status into this file, MEMORY.md, or Serena memories — reference STATUS.md.
Current Sprint
See STATUS.md for the active phase, what's done, and what's next.
Stack

Layout
src/index.ts— MCP server entry / composition root. Computes which apps are enabled from env vars at startup, then decides transport (stdio vs HTTP) based onMCP_PORT. Per-sessionMcpServerinstances via thecreateServer()factory; client instances are computed once at startup.src/clients/base.ts—ServarrClientbase class with shared HTTP plumbing (X-Api-Keyauth, request helper, common endpoints: systemStatus, queue, history). Also exports theasText()helper.src/clients/<app>.ts— one file per app, holding only the<App>Clientclass (subclass ofServarrClientwith app-specific resource methods). Today:sonarr.ts,radarr.ts,lidarr.ts,readarr.ts,prowlarr.ts.src/tools/<app>/index.ts— MCP tool registrations for that app. Each exports aregister<App>Tools(server, client)function. Today each app'sindex.tsholds all of that app's registrations directly. As tool counts grow, pull resource groups into sibling files (series.ts,wanted.ts, etc.) — see "Per-resource splitting" below.docs/SERVARR-API.md— cross-cutting Servarr API reference (auth, paging, command pattern, errors).docs/<app>.md— per-app endpoint catalogue + tool decisions (current tools, candidate read/write tools, out-of-scope, gotchas).docs/specs/<app>.json— version-pinned OpenAPI spec snapshots.Dockerfile— multi-stage build (alpine, non-root)docker-compose.yml— Compose/Portainer deployment using HTTP transport.githooks/pre-commit— gitleaks + PII pattern scan
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.

servarr-mcp AGENTS.md is an instructions file published in the GitHub repository CarlDog/servarr-mcp (0 stars, last pushed yesterday), licensed MIT. It adds 2,460 tokens to every session, about $0.0123 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
