## Direct answer

AllSource Core is a Rust event-store database for ordered, immutable events, replay, and point-in-time state. Query Service separates tenant-scoped HTTP, realtime, analytics, and projection reads over Core without another primary database. Prime derives graph, vector, temporal, and provenance-aware agent memory. Hosted AllSource operates tenant authentication, quotas, billing, and public APIs. Separate MCP connectors expose event-store or Prime tools.

AllSource at all-source.xyz is unrelated to Esri ArcGIS AllSource, all-source intelligence, and other companies using similar names.

## Verified product facts

- Core durability: CRC32-checked WAL plus Parquet persistence.
- Published reference: 469K events/sec batch ingestion.
- Published reference: 11.9µs p99 Core indexed reads.
- MCP: 45 read-only tools, 55 default tools, 73 with fleet and administration.
- Prime MCP: separate memory registry; never add its tool count to event-store MCP.
- Hosted plans: Indie £18.99/mo; £181.99/year. Studio £78.99/mo; £757.99/year. Scale £298.99/mo; £2,869.99/year.
- Event-store MCP registry: 55  default (remote, writes enabled); 64  with ALLSOURCE_CONTROL_URL set.
- Core/community licence: Apache-2.0; designated enterprise components use BSL 1.1.
- No PostgreSQL required by current AllSource services; Core owns durable event history.

Benchmark reference: 11.9us p99 indexed reads. Benchmark numbers describe named Core paths, not hosted HTTP, vector, graph, hybrid recall, or every durability configuration.
