Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Framework


A workflow MCP server over a self-hosted Jellyseerr / Overseerr instance — the request layer that fronts Jellyfin/Plex/Emby plus Radarr and Sonarr. The unit of work is not "download a movie"; it is search → resolve the exact TMDB-backed title → check availability and request state → create a guarded request that Radarr/Sonarr act on. Jellyseerr owns permissions, quotas, routing, and status; this server never touches Radarr/Sonarr directly.

Two properties make it safe to hand an agent:

  • Guarded writes. The one mutating tool (seerr_request_media) defaults to mode: preview — it resolves the title and returns the exact payload that would be submitted without writing anything. The real request fires only on mode: request, and asks for an explicit confirmation first when the client supports elicitation.
  • PII/infra redaction. Raw Jellyseerr payloads carry operator email, Plex/Jellyfin tokens, internal service URLs, and filesystem paths. A single normalization choke point strips all of it before any tool output — requester objects are projected to { id, displayName }, and root-folder paths are gated behind an explicit includePaths flag.

Tools

Six tools covering the request workflow — discover (search) → confirm (get) → understand routing (service_options) → request (request_media) → track (request_status / list_requests):

| Tool | Description | |:---|:---| | seerr_search_media | Search movies and TV by title; returns ranked matches with TMDB ID, year, overview, and decoded availability when Jellyseerr already tracks the title. The required first step before requesting. | | seerr_get_media | Fetch exact movie/show details by TMDB ID + media type to confirm the title before a write; for TV, a per-season summary or one season's episode list. | | seerr_list_requests | List recent requests with status/type/requester filters; echoes the applied filters and decodes every numeric status. | | seerr_request_media | Guarded write. Previews the request payload by default (mode: preview); creates the request only on mode: request with an elicited confirmation. | | seerr_request_status | Fetch one request by ID — decoded request + media availability (incl. 4K), requester, routing summary, and a state-tuned next-step hint. | | seerr_service_options | Summarize configured Radarr/Sonarr services, default quality profiles, and instance capability flags (4K, partial requests, specials, media server). Filesystem paths redacted unless includePaths. |

Every status field is decoded to { raw, label } — both the numeric code Jellyseerr returns and a human label — so an agent never has to hardcode the enum mapping.

seerr_search_media

Title disambiguation entry point. Wraps GET /search, filters to movies and TV (people are always excluded), and decodes availability when the title is tracked.

  • Free-text title queries matched against TMDB; movie / tv / all media-type filter
  • Decoded availability (status, plus status4k when 4K is enabled) for tracked titles only
  • Pagination by page, with a per-call result limit to cap output size
  • Optional ISO 639-1 language for localized titles/overviews
  • Empty results are a normal success — returns [] with a guidance notice, not an error

seerr_get_media

Confirm the exact title before a write. Wraps GET /movie/{id} or GET /tv/{id}, optionally a season's episodes.

  • Availability plus any existing open request for the title (avoids duplicate requests)
  • TV: omit seasonNumber for a per-season summary, or pass one to fetch that season's episode list (season 0 is Specials)
  • A TMDB ID that doesn't resolve surfaces as a clean media_not_found with a search-recovery hint (Jellyseerr's raw HTTP 500 is classified in the service layer)

seerr_list_requests

Review recent requests and their lifecycle. Wraps GET /request.

  • Lifecycle filter (pending, processing, available, failed, …), mediaType, and requestedById filters
  • Sort by created (added) or last-changed (modified), ascending or descending
  • take / skip pagination; the enrichment trailer echoes the filter set the server applied
  • Requester is PII-redacted to { id, displayName }; titles aren't on request objects, so they're omitted here — fetch one with seerr_get_media when needed

seerr_request_media

The only mutation in the surface, and it is triple-guarded:

  1. mode: preview (default) resolves the title and returns the exact POST /request payload that would be submitted — no write. A sloppy call shows the payload and changes nothing.
  2. mode: request triggers a ctx.elicit confirmation when the client supports it; declining cancels before submission.
  3. destructiveHint: true is the fallback signal for non-interactive clients whose approval flow reads annotations.
  • Capability validation (4K enabled? seasons valid? partial requests allowed?) runs locally against cached instance settings before any POST, so a bad request fails with an actionable typed error instead of a failed write
  • TV requests take seasons: "all" or an explicit list (e.g. [1, 2]); Specials are excluded unless the instance enables them
  • Optional routing overrides (serverId, profileId, rootFolder, languageProfileId) — omit to use Jellyseerr's defaults (recommended)
  • An existing request for the title is surfaced in the output; a duplicate rejection from Jellyseerr maps to a typed duplicate_request pointing back at it

seerr_service_options

Lets an agent reason about request capability and routing without a separate status tool. Fans out service + settings + version reads with Promise.allSettled, so one failed leg degrades to a disclosed notice rather than failing the call.

  • Instance capability summary: Jellyseerr version, media server, and the movie4kEnabled / series4kEnabled / partialRequestsEnabled / specialEpisodesEnabled flags
  • Per-service routing: server ID, default-server flag, 4K capability, and the active + available quality profiles (IDs and names, safe to surface)
  • Filesystem root-folder paths and free space are operator-private — omitted unless includePaths: true

Resource and prompt

| Type | Name | Description | |:---|:---|:---| | Resource | seerr://request/{requestId} | Read-once summary of one request — decoded status + media availability + routing. Mirrors seerr_request_status. |

All request data is also reachable via tools — request enumeration is the job of seerr_list_requests (filterable, the tool-only access path), so the collection is intentionally not exposed as a resource. There are no prompts; the guarded-write workflow lives in the tool, not a prompt template.

Features

Built on @cyanheads/mcp-ts-core:

  • Declarative tool and resource definitions — single file per primitive, framework handles registration and validation
  • Unified error handling — handlers throw, framework catches, classifies, and formats
  • Pluggable auth: none, jwt, oauth
  • Swappable storage backends: in-memory, filesystem, Supabase, Cloudflare KV/R2/D1
  • Structured logging with optional OpenTelemetry tracing
  • STDIO and Streamable HTTP transports

Jellyseerr-specific:

  • Read + guarded-request only — admin-scope endpoints (approve/decline, retry, edit/delete, media/file deletion, user/settings/sync) are excluded by design, not by API limitation
  • Status decoding centralized in one helper — request and media statuses (including the separate 4K availability) decode to { raw, label } everywhere, forward-compatible with new Jellyseerr status codes
  • Capability validation against cached instance settings catches most bad requests before they reach the API
  • A short-TTL settings cache avoids a round-trip on every preview

Agent-friendly output:

  • Mandatory PII/infra redaction — a single normalization choke point projects requester objects to { id, displayName } and drops operator email, Plex/Jellyfin tokens, internal serviceUrl, and filesystem paths before any output reaches the model
  • Provenance and disclosure — searches echo the effective query; capped lists disclose truncation; a degraded service leg surfaces a notice instead of silently dropping data
  • Typed, actionable errorsmedia_not_found, request_not_found, seasons_required, four_k_not_enabled, duplicate_request, and more carry a recovery hint so callers can branch and retry without parsing prose

Getting started

This server connects to your own Jellyseerr/Overseerr instance — there is no public hosted endpoint. Add the following to your MCP client configuration file, pointing SEERR_BASE_URL at your instance and supplying its API key.

{
  "mcpServers": {
    "seerr-mcp-server": {
      "type": "stdio",
      "command": "bunx",
      "args": ["@cyanheads/seerr-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "MCP_LOG_LEVEL": "info",
        "SEERR_BASE_URL": "http://localhost:5055",
        "SEERR_API_KEY": "your-api-key"
      }
    }
  }
}

Or with npx (no Bun required):

{
  "mcpServers": {
    "seerr-mcp-server": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@cyanheads/seerr-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "MCP_LOG_LEVEL": "info",
        "SEERR_BASE_URL": "http://localhost:5055",
        "SEERR_API_KEY": "your-api-key"
      }
    }
  }
}

For Streamable HTTP, set the transport and start the server:

MCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 SEERR_BASE_URL=http://localhost:5055 SEERR_API_KEY=your-api-key bun run start:http
# Server listens at http://localhost:3010/mcp

Prerequisites

  • Bun v1.3.2 or higher (or Node.js v24+).
  • A running Jellyseerr or Overseerr instance, and its API key (Settings → General → API Key).

Installation

  1. Clone the repository:
git clone https://github.com/cyanheads/seerr-mcp-server.git
  1. Navigate into the directory:
cd seerr-mcp-server
  1. Install dependencies:
bun install
  1. Configure environment:
cp .env.example .env
# edit .env — set SEERR_BASE_URL and SEERR_API_KEY

Configuration

All configuration is validated at startup via Zod schemas in src/config/server-config.ts. Key environment variables:

| Variable | Description | Default | |:---|:---|:---| | SEERR_BASE_URL | Required. Base URL of the Jellyseerr/Overseerr instance, e.g. http://localhost:5055. The service appends /api/v1 — no /api/v1 suffix, no trailing slash. | — | | SEERR_API_KEY | Required. Jellyseerr API key (Settings → General → API Key). Sent as the X-Api-Key header. | — | | SEERR_REQUEST_TIMEOUT_MS | Per-request HTTP timeout in milliseconds. | 15000 | | MCP_TRANSPORT_TYPE | Transport: stdio or http. | stdio | | MCP_HTTP_PORT | Port for the HTTP server. | 3010 | | MCP_AUTH_MODE | Auth mode: none, jwt, or oauth. | none | | MCP_LOG_LEVEL | Log level (RFC 5424). | info | | LOGS_DIR | Directory for log files (Node.js only). | <project-root>/logs | | STORAGE_PROVIDER_TYPE | Storage backend. | in-memory | | OTEL_ENABLED | Enable OpenTelemetry instrumentation. | false |

See .env.example for the full list of optional overrides.

Running the server

Local development

  • Build and run:

    # One-time build
    bun run rebuild
    
    # Run the built server
    bun run start:stdio
    # or
    bun run start:http
  • Run checks and tests:

    bun run devcheck   # Lint, format, typecheck, security, changelog sync
    bun run test       # Vitest test suite
    bun run lint:mcp   # Validate MCP definitions against spec

Docker

docker build -t seerr-mcp-server .
docker run --rm \
  -e SEERR_BASE_URL=http://host.docker.internal:5055 \
  -e SEERR_API_KEY=your-api-key \
  -p 3010:3010 \
  seerr-mcp-server

The Dockerfile defaults to HTTP transport, stateless session mode, and logs to /var/log/seerr-mcp-server. OpenTelemetry peer dependencies are installed by default — build with --build-arg OTEL_ENABLED=false to omit them.

Project structure

| Directory | Purpose | |:---|:---| | src/index.ts | createApp() entry point — registers the six tools + one resource and inits the Seerr service. | | src/config | Server-specific environment variable parsing and validation with Zod. | | src/mcp-server/tools | Tool definitions (*.tool.ts). | | src/mcp-server/resources | Resource definitions (*.resource.ts). | | src/services/seerr | Jellyseerr API client, status decoders, and the PII/infra redaction normalizers. | | tests/ | Unit and integration tests mirroring src/. |

Development guide

See CLAUDE.md/AGENTS.md for development guidelines and architectural rules. The short version:

  • Handlers throw, framework catches — no try/catch in tool logic
  • Use ctx.log for request-scoped logging, ctx.state for tenant-scoped storage
  • Register new tools and resources via the barrels in src/mcp-server/*/definitions/index.ts
  • Wrap the Jellyseerr API: validate raw → normalize and redact to a domain type → return the output schema; never fabricate missing fields, and never let operator PII or paths reach output
