What is servarr-mcp CLAUDE.md?

Project guidance for working on servarr-mcp, a Docker-based server that connects media-management apps such as Sonarr and Radarr to coding tools.

Use it when changing or reviewing the servarr-mcp codebase, especially its TypeScript server, app connections, Docker setup, or project status.

It gives the agent the project’s current status, technology choices, file layout, and rules for keeping project information in the right place.

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	$0.02726	$0.02726
Opus 5	$0.01363	$0.01363
Sonnet 5	$0.00545	$0.00545
Haiku 4.5	$0.00273	$0.00273

Security

Grade A, and why

servarr-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 5d 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.

Origin

This is a copy

91% identical to servarr-mcp AGENTS.md — 30 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 233 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

TypeScript (Node 22+, ESM, NodeNext module resolution)
@modelcontextprotocol/sdk (high-level McpServer API)
zod for tool input schemas
Servarr REST APIs accessed directly via fetch (no third-party client)
Docker multi-stage build (alpine, non-root user)

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 on MCP_PORT. Per-session McpServer instances via the createServer() factory; client instances are computed once at startup.
src/clients/base.ts — ServarrClient base class with shared HTTP plumbing (X-Api-Key auth, request helper, common endpoints: systemStatus, queue, history). Also exports the asText() helper.
src/clients/<app>.ts — one file per app, holding only the <App>Client class (subclass of ServarrClient with 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 a register<App>Tools(server, client) function. Today each app's index.ts holds 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.
