@cyanheads/seerr-mcp-server
Search Jellyseerr/Overseerr, check availability, and create guarded media requests via MCP. STDIO or Streamable HTTP.
Overview
Jellyseerr and Overseerr media-request workflow: search TMDB-backed titles, confirm the exact match, check availability and request state, and create a guarded request that Radarr/Sonarr act on. Jellyseerr owns permissions, quotas, routing, and status — this server never calls Radarr/Sonarr directly. Runs as a stdio process or a local Streamable HTTP server.
Tools
| 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. Titles are opt-in via includeTitles. |
seerr_request_media | Guarded write. Previews the request payload by default (mode: preview); creates the request only on mode: request, and only after an accepted confirmation. |
seerr_request_status | Fetch one request by ID — title, 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. |
Resources
| Resource | Description |
|---|---|
seerr://request/{requestId} | Read-once summary of one request — decoded status, media availability, requester, and routing. Mirrors seerr_request_status. |
All request data is also reachable via tools — request enumeration is the job of seerr_list_requests (the tool-only access path).
Capability reference
seerr_search_media tool
- Search titles with
mediaType: movie | tv | all; people are excluded.pageis 1–1000;limitis 1–20, default 10. - Returns TMDB matches and decoded
status/status4kfor tracked titles. Empty results return[]with a guidance notice. - Optional ISO 639-1
languageselects localized titles and overviews.
seerr_get_media tool
- Availability plus any existing open request for the title (avoids duplicate requests)
- TV: omit
seasonNumberfor 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 typed
media_not_foundwith a search-recovery hint (Jellyseerr's raw HTTP 500 is classified in the service layer)
seerr_list_requests tool
- Filter by lifecycle
filter,mediaType, andrequestedById; sort byaddedormodified, ascending or descending.takeis 1–100, default 20;skipselects the offset. - Returns decoded statuses, requester
{ id, displayName }, and an enrichment trailer with applied filters. includeTitles: truejoins media titles once per distinct title (default off); unresolved rows retain their data and are disclosed in the notice.
seerr_request_media tool
- Guarded write.
mode: preview(default) returns the resolved title and exactPOST /requestpayload without writing.mode: requestasks for confirmation bound to the same caller, title and payload; declined, cancelled or invalid answers returnrequest_cancelled. - TV requests require
seasons: "all"or a list such as[1, 2]; season 0 (Specials) requires special episodes to be enabled. Instance capability checks run before any POST; existing requests appear in output and duplicate rejections returnduplicate_request. - Optional routing overrides:
serverId,profileId,rootFolder,languageProfileId. Omit them to use Jellyseerr's defaults.
seerr_request_status tool
- Accepts
requestIdfromseerr_request_media'screated.requestIdorseerr_list_requests. A missing request returnsrequest_not_found. - Returns decoded
requestStatus,mediaStatus/mediaStatus4k, requester{ id, displayName }, routing (serverId,profileName,is4k), andstateGuidance. - Joins
titleon each call; it is absent when notmdbIdexists or the lookup fails.
seerr_service_options tool
- Returns instance version, media server, capability flags (
movie4kEnabled,series4kEnabled,partialRequestsEnabled,specialEpisodesEnabled), and service IDs, defaults and quality profiles. - Failed service legs retain the available results with a notice.
includePaths: trueexposes root-folder paths and free space; both are omitted by default.
seerr://request/{requestId} resource
- Accepts
requestIdfromseerr_request_mediaorseerr_list_requests; a missing request returnsrequest_not_found. - Mirrors
seerr_request_status, including redaction and a title join.titleis absent when notmdbIdexists or the lookup fails; resources take no per-read options.
Features
Built on @cyanheads/mcp-ts-core: stdio and Streamable HTTP transports, pluggable auth (none / jwt / oauth), swappable storage (in-memory, filesystem, Supabase, Cloudflare KV/R2/D1), structured logging with optional OpenTelemetry tracing.
HTTP requires stateful sessions for 2025-era confirmation rounds; explicit MCP_SESSION_MODE=stateless fails startup. Consent records expire after ten minutes and changed or replayed records ask again. Redemption excludes concurrent retries in one process; request creation makes one POST attempt without automatic retries. Cross-instance read-and-delete is not atomic: use shared strongly consistent filesystem, Supabase or Cloudflare D1 storage for routed retries, and account for duplicate-submission races; Cloudflare KV is unsuitable for consent records.
Seerr-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
- PII/infra redaction centralized in one normalizer choke point — requesters project to
{ id, displayName }; operator email, Plex/Jellyfin tokens, andserviceUrlnever reach output; filesystem paths are opt-in viaincludePaths - 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:
- 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 errors —
media_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
Add the following to your MCP client configuration file, pointing SEERR_BASE_URL at your own Jellyseerr or Overseerr 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 v1.4.0 or higher (or Node.js v24+).
- A running Jellyseerr or Overseerr instance, and its API key (Settings → General → API Key).
Installation
- Clone the repository:
git clone https://github.com/cyanheads/seerr-mcp-server.git
- Navigate into the directory:
cd seerr-mcp-server
- Install dependencies:
bun install
- 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 |
MCP_SESSION_MODE | HTTP session mode; must resolve to stateful for confirmation rounds. The example and Docker image set stateful; an unset value uses auto, resolving to stateful. Explicit stateless fails startup. | auto |
MCP_REQUEST_STATE_KEY | Optional key of at least 32 bytes, shared across instances, that seals consent record IDs. | — |
OTEL_ENABLED | Enable OpenTelemetry instrumentation. | false |
OTEL_EXPORTER_OTLP_ENDPOINT | OTLP base for traces and metrics; signal-specific endpoints override it. | — |
OTEL_EXPORTER_OTLP_LOGS_ENDPOINT | Opt-in log export endpoint; the base endpoint never enables logs. | — |
LOG_TOOL_FAILURE_PAYLOADS | Opt-in failed-call arguments/result logging; redaction matches key names, so secrets in free-form values can remain. | false |
See .env.example for the full list of optional overrides.
Running the server
Local development

Development guide
See CLAUDE.md/AGENTS.md for development guidelines and architectural rules. The short version:
- Handlers throw, framework catches — no
try/catchin tool logic - Use
ctx.logfor request-scoped logging,ctx.statefor 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
