Agent builders

Give your agent a memory it can cite.

27 MCP tools and a REST API for agents that remember customers. Typed claims, linked to their sources, on a SQLite file you run.

Where agent memory goes wrong.

  1. 01

    Notes, not facts

    Free-text memory can't be queried, compared or corrected field by field.

  2. 02

    No source to show

    When a user asks why the agent believes something, there's nothing to point to.

  3. 03

    Silent overwrites

    New information replaces old, and the agent never notices the two disagreed.

Scenarios

What your agent can do with it.

How OpenCRM answers

It fetches the observation and returns the email it was taken from.

What you get.

  • Typed memoryEntities, relationships and claims with schemas, not free text.
  • Answers with sourcesEvery claim links to the artifact it came from.
  • Disagreements handledConflicts are first-class, so your agent can ask instead of guess.
  • Nothing to host but a fileSQLite, Node and Apache 2.0. Run it next to your agent.

Under the hood.

  • A source for each field

    Observations name the field they cover and cite the artifact behind it.

  • Append-only event log

    Entity changes are logged with their diff and never edited.

  • Agent attribution

    Entity writes can carry the agent id, tool call id and prompt hash.

  • Content hashes

    Each artifact is stored with a SHA-256 hash of its text.

  • Export

    Take every record out as JSON, whenever you need it.

  • Self-hosted

    One SQLite file on infrastructure you control.

Questions.

Does it do vector search?

No. It has structured filters and SQLite full-text search. Vector search isn't built.

Which agents can use it?

Any MCP client that can start a stdio server, including Claude Desktop and Claude Code, and anything that speaks HTTP through the REST API.

Can I change the entity types?

Entity types are fixed: contact, company, deal, interaction, task and agent. Each entity's properties are free-form JSON.
