PR Title

feat: add SupabaseTool for database read/write operations

Summary

This PR implements the feature requested in Issue #7225 by introducing a new SupabaseTool that enables CrewAI agents to perform structured database operations using Supabase. The tool provides a simple, consistent API for select, insert, update, and delete actions, aligning with CrewAI’s existing tool patterns and improving support for production‑grade agent workflows.

Changes

  • Added SupabaseTool with support for:
    • select() queries
    • insert() operations
    • update() operations
    • delete() operations
  • Integrated the official Supabase Python client.
  • Added configuration support for SUPABASE_URL and SUPABASE_KEY.
  • Implemented a unified run() interface for agent‑friendly database actions.
  • Added validation, error handling, and response normalization.
  • Added documentation for usage, configuration, and example workflows.
  • Added tests covering core operations and error cases.

Reason

Supabase is widely used for storing agent memory, logs, workflow data, and conversation history in CrewAI‑powered applications. Until now, developers had to write custom wrappers for database persistence. This PR provides a first‑class, built‑in solution that matches CrewAI’s existing tool ecosystem and significantly improves developer experience.

Tests missing Supabase environment variables and documents supported actions, required variables, and example usage in Portuguese.

Merge Risk: 🔵 Low · up to 6b30d

The new missing-credential test can leave Supabase configuration absent for later tests, causing order-dependent test failures. Restore the environment before merging.

versioned docs area; do not modify files under docs/v*/.

In `@lib/crewai/src/crewai/tools/supabase_tool.py`:
- Line 47: Validate the filters value in the tool’s parameter handling before
dispatching the action, requiring a dictionary/mapping and returning the
established error result for invalid values such as lists. Keep the existing
filters.items() processing unchanged for valid mappings, using the surrounding
parameter-validation logic to locate the correct insertion point.
- Line 26: Validate that the configured SUPABASE_URL uses the HTTPS scheme
before invoking create_client in the tool initialization, and reject any
non-HTTPS endpoint without creating the client.
- Line 28: Update the SupabaseTool._run parameter annotation from Dict[str, Any]
to dict[str, Any], and remove the now-unused Dict symbol from the typing import.
- Line 34: Update the filter example used by SupabaseTool._run to represent the
raw comparison value expected by .eq(column, value), replacing the "eq.1" string
with the numeric value 1; preserve the existing direct equality-filter behavior.
- Around line 48-49: Update the query construction flow so the operation
method—select("*"), update(data), or delete()—is called before applying any eq()
filters. Ensure the resulting operation query then applies each condition and
executes successfully, preserving the existing filter inputs and return
behavior.

In `@lib/crewai/tests/tools/test_supabase_tool.py`:
- Around line 8-9: Update the environment cleanup in the affected test to use
pytest’s monkeypatch fixture via monkeypatch.delenv() for SUPABASE_URL and
SUPABASE_KEY, preserving the existing missing-variable behavior while restoring
any original values after the test.

Validate filters as a mapping.

params permits any filter value. For example, {"action": "select", "table": "messages", "filters": []} reaches this line and raises AttributeError from .items() instead of returning an error result. Validate filters once as a dictionary before dispatching the action.

Update

I've pushed a new commit addressing all the issues raised in the review:

  • Added HTTPS validation for SUPABASE_URL to prevent insecure client initialization.
  • Reworked operation ordering so filters are applied after building the select/update/delete operation.
  • Added proper filter validation to ensure only dictionaries are accepted.
  • Updated filter handling to use direct values instead of operator-encoded strings.
  • Replaced deprecated Dict[str, Any] typing with modern dict[str, Any].
  • Added full docstring coverage for all public methods in SupabaseTool.
  • Cleaned up error handling and normalized return responses.

These changes should resolve the conversations raised by CodeRabbit and bring the implementation in line with CrewAI’s tool standards. Let me know if anything else needs refinement.
