From finding it to leaving

What an agent managed without a person, at each step.

  1. Find

    On its own

    Docs it can act on: llms.txt, an OpenAPI and an MCP server.

    485 doc pages read

  2. Get in

    On its own

    Runs locally, sign-up in a browser.

    3 minutes

  3. Use

    On its own

    Did: create collections and store objects, with the server making the embeddings; search by meaning, by keyword, by both, and with filters.

    10 of 10 core tasks

  4. Pay

    Reaches the checkout

    Stopped at the $45 a month charge.

  5. Leave

    On its own

    Nothing to cancel, deletes its account.

  • What it can't do, and why

    • Sign up and get the first key without a browser Sign-up and the first key are made in the web console.
    • Use GraphQL on a new free cluster The cluster answers that it is switched off.
    • Generate text with a model Needs a model provider key we did not have.
    • Back up a cloud cluster The free cluster's admin key is refused.
    • Buy a paid plan Only through a card form; no billing API or agent payment.

Paid-plan tasks don't count toward the level. The drive used the free plan.

Tips for agent builders

From this drive

7 tips
  1. After the first console key, create scoped keys with POST /v1/users/db/{id} and assign roles with POST /v1/authz/users/{id}/assign.
  2. Search with POST /v1/search/{collection}/near-text|bm25|hybrid or gRPC via the SDK; GraphQL may answer 410.
  3. On free clusters leave vectorIndexType unset (only hfresh) and expect one collection.
  4. REST hybrid fusionType takes ranked or relativeScore.
  5. Send X-Weaviate-Cluster-Url with Weaviate Embeddings collections.
  6. Query Agent MCP: https://api.agents.weaviate.io/mcp with Authorization: Bearer <cluster key> and X-Weaviate-Cluster-Url; use initialize (2025-11-25).
  7. Engram: use https://api.engram.weaviate.io/v1/...; poll GET /v1/runs/{run_id}; send user_id for user-scoped topics.
