Block Tools

The pull_block tool downloads and installs a block’s package dependencies.

Parameters

Example Request

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "pull_block",
    "arguments": {
      "block_name": "stackie.postgres"
    }
  }
}

Idempotency

pull_block is idempotent. Re-pulling an already-installed block at the same version only updates the last_used_at timestamp in the database. It does not re-download binaries that are already present.

Block Name Format

Block names follow the pattern [namespace.]name. Built-in blocks use the stackie. prefix (e.g., stackie.postgres, stackie.redis). Omitting the namespace uses the default registry lookup.
