Domain knowledge for Mozilla Remote Settings — workflow patterns, data models, and gotchas for your AI agent.
Public read-only access to Firefox's configuration and content delivery infrastructure. Built on the Kinto protocol. No authentication required.
Production Remote Settings—the configuration surface Firefox clients poll—is organized hierarchically: Bucket → Collection → Record.
Buckets — top-level namespaces. The primary production bucket is main. Others include blocklists, security-state, and monitor/changes for polling.
Collections — datasets within a bucket. Each collection has a schema, last-modified timestamp, and metadata. Common collections in main:
Records — individual data entries within a collection. The actual configuration data Firefox consumes. Each record has an id and last_modified timestamp.
Groups — permission groups within a bucket. Define who can read/write collections.

Execute multiple Kinto HTTP operations in one request. Pass a body with 'requests' (each with path, method, optional headers/body) and optional 'defaults' applied to every sub-request. Reduces round-trips for bulk reads or writes.
Contribute
Invoke the server-specific contribute.json endpoint (Mozilla Kinto deployment). Returns contribution or telemetry metadata as defined by that instance — not part of the core Kinto CRUD API.
Create Attachment
Upload or attach a file to an existing record via the attachment sub-resource. Requires bucket_id, collection_id, and record id. The request body is handled by the Kinto attachment API (multipart as required by the server).
Delete Attachment
Remove the binary attachment associated with a record. Requires bucket_id, collection_id, and record id. Destructive — the attachment cannot be recovered.
Get Bucket
Fetch a single bucket by id (permissions, last modified, optional collection hints). Optional fields trims the response. List buckets first when you need to discover bucket ids.
Get Buckets
List Kinto buckets (top-level containers). Supports pagination (limit, token), sorting (sort), time filters (since, to, before), and field projection (fields). Start here to discover bucket IDs before opening collections or records.
Get Changes
Read change-monitor records under buckets/monitor/collections/changes — the stream of mutations for sync and replication. Use with since/token for incremental updates across clients.
Get Collection
Fetch metadata for one collection inside a bucket (schema, permissions summary, revision). Pass bucket_id and collection id. Optional fields trims the response.
Get Collection Changeset
Fetch a collection changeset for offline-first sync. Requires bucket id (bid), collection id (cid), and expected (expected collection revision). Optional since and limit bound the delta. Use when reconciling local state with the server.
Get Collections
List collections inside a bucket. Pass bucket_id; optional limit, sort, token, time filters, and fields. After listing, read documents by listing records in the chosen collection with the same bucket_id and collection_id.
Get Group
Fetch one group by id within a bucket. Returns member principals and group metadata. Optional fields limits returned attributes.
Get Groups
List permission groups defined on a bucket. Groups bundle principals for ACLs. Pass bucket_id; supports the usual Kinto list parameters (limit, token, sort, time filters, fields).
Get Openapi Spec
Fetch the OpenAPI specification for this Kinto instance. Use it to discover paths, parameters, and response shapes when building or debugging integrations.
Get Record
Fetch a single record by id within a bucket and collection. Optional fields limits which attributes are returned. List records in the collection first when you need to discover record ids.
Get Records
List JSON records in a collection. Requires bucket_id and collection_id. Supports pagination, sort, continuation token, time filters, filter by record id, and fields to trim payloads. When you already know a single record id, fetch that record individually with bucket_id, collection_id, and id instead of listing.
Kinto Heartbeat
Lightweight liveness probe for the Kinto API. Confirms the service responds; use for health checks or connectivity validation.
Kinto Lb Heartbeat
Load-balancer heartbeat endpoint. Confirms the node behind the LB is reachable; typically used by infrastructure, not for application data.
Kinto Version
Return the deployed Kinto server version string. Use when reporting issues or matching behavior to a specific release.
Server Info
Return Kinto server metadata at the API root (capabilities, protocol version, and feature flags). Call this first to understand what the server supports before using buckets, collections, or batch operations.
Mozilla Remote Settings is a configuration and data distribution service used by Firefox to manage settings, rules, and content updates. Access Firefox configuration data, retrieve remote settings, and query Mozilla's content delivery infrastructure. It provides 19 tools that AI agents can use through the Model Context Protocol (MCP).
Add the MCPBundles server URL to your MCP client configuration (Claude Desktop, Cursor, VS Code, etc.). The URL format is: https://mcp.mcpbundles.com/bundle/mozilla-com-kinto. Authentication is handled automatically.
Mozilla Remote Settings provides 19 tools that can be called by AI agents, along with a SKILL.md that gives your AI agent domain knowledge about when and how to use them.
Mozilla Remote Settings uses open data APIs — no authentication required.
