past.dev
Context and memory API that captures work history and serves it back to agents over REST and MCP
past.dev is a memory layer for AI agents. It ingests events from the tools a team already uses, resolves them into entities, and answers questions about that history over a REST API or an MCP server, so an agent can ask what happened on a project rather than being re-told in every prompt.
Usage is metered in credits, one per 350 bytes ingested. Pay as you go has no monthly fee and starts with $45 of credits ($120 with a work email), no card. Flex is $99/month for 400,000 credits and unlimited recall calls. Sign-up is self-serve.
Pricing: Usage-based (credits)
