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.

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

plex-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 yesterday.

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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

plex-mcp

MCP server for Plex Media Server, packaged as a Docker container.

Fleet standards: ts-mcp-server v1.0 — audited 2026-07-25

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
  • Plex HTTP API via fetch (no Plex SDK dependency)
  • Docker multi-stage build (alpine, non-root)

Layout

  • src/index.ts — MCP server entry. Decides transport based on MCP_PORT.
  • src/mcp-route.ts — the Streamable HTTP /mcp route: Host/Origin allowlist, per-session transport map, idle sweep, session dispatch. Split out of index.ts so it can be imported by a test — index.ts self-executes on import, so nothing in it was reachable without booting a server. Covered by tests/mcp-route.test.ts.
  • src/plex.ts — Plex HTTP API client.
  • src/tautulli.ts — optional direct Tautulli HTTP client, fail-soft config, normalized privacy-allowlisted response types.
  • src/log.ts — small structured logger (stderr, level-gated via LOG_LEVEL env var). See README for format and levels.
  • src/tools/ — tool registrations split per domain (discovery.ts, sessions.ts, playback.ts, playlists.ts, hubs.ts, admin.ts, images.ts, diagnostics.ts, tautulli.ts). index.ts orchestrates via registerTools(server, plex, tautulli); helpers.ts holds shared utilities (asText, withLogging).
  • Dockerfile — multi-stage build for the runtime image.
  • docker-compose.yml — Compose/Portainer deployment using HTTP transport.
  • docs/PLEX-API.md — curated reference for the Plex HTTP API: external doc links, gotchas we've hit (pagination pairing, /:/scrobble empty responses, type integer codes), and rough endpoint shapes for capabilities we haven't built yet. Read this before adding new tools.
  • docs/CHATGPT-APPS-SDK.md — future-work spec for making plex-mcp consumable from a ChatGPT account (OAuth 2.1 protected-resource setup, tool annotation hints, optional UI widgets, infrastructure choices). Not started; phased plan inside.
  • .githooks/pre-commit — gitleaks + PII pattern scan.
  • .gitleaks.toml — secret-scanning config.

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.
