From c5a94faa33668b8bb1bca54927b0e0430dd236b2 Mon Sep 17 00:00:00 2001 From: Brian O'Kelley Date: Mon, 27 Oct 2025 12:52:23 -0400 Subject: [PATCH 01/13] fix: Return human-readable text in MCP protocol messages MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem MCP tools were returning Pydantic response objects directly, causing FastMCP to serialize them to JSON and display the JSON string in the "Protocol Message" field instead of human-readable text. Example before: ``` Protocol Message: {"publisher_domains":["weather.com"],"primary_channels":null,...} ``` ## Solution Modified all 11 MCP tool wrapper functions to return `ToolResult` objects with separate content and structured_content fields: - content: Human-readable text from __str__() method - structured_content: JSON data from model_dump() Example after: ``` Protocol Message: Found 1 authorized publisher domain: weather.com ``` ## Changes Updated MCP wrapper functions in: - src/core/tools/properties.py (list_authorized_properties) - src/core/tools/products.py (get_products) - src/core/tools/creative_formats.py (list_creative_formats) - src/core/tools/creatives.py (sync_creatives, list_creatives) - src/core/tools/signals.py (get_signals, activate_signal) - src/core/tools/media_buy_create.py (create_media_buy) - src/core/tools/media_buy_update.py (update_media_buy) - src/core/tools/media_buy_delivery.py (get_media_buy_delivery) - src/core/tools/performance.py (update_performance_index) Pattern applied: ```python from fastmcp.tools.tool import ToolResult response = _tool_impl(...) return ToolResult( content=str(response), # Human-readable text structured_content=response.model_dump() # JSON data ) ``` Also updated AdCP schemas to latest versions. ## Testing āœ… All imports verified āœ… Unit tests passing āœ… Maintains backward compatibility (_impl and _raw functions unchanged) šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- ...dia-buy_create-media-buy-request_json.json | 8 +------ ...dia-buy_update-media-buy-request_json.json | 13 ++++++----- src/core/tools/creative_formats.py | 9 +++++--- src/core/tools/creatives.py | 19 +++++++++++----- src/core/tools/media_buy_create.py | 9 +++++--- src/core/tools/media_buy_delivery.py | 9 +++++--- src/core/tools/media_buy_update.py | 9 +++++--- src/core/tools/performance.py | 9 +++++--- src/core/tools/products.py | 11 +++++++--- src/core/tools/properties.py | 13 ++++++++--- src/core/tools/signals.py | 22 ++++++++++++------- 11 files changed, 85 insertions(+), 46 deletions(-) diff --git a/schemas/v1/_schemas_v1_media-buy_create-media-buy-request_json.json b/schemas/v1/_schemas_v1_media-buy_create-media-buy-request_json.json index fc40ee80a..cda3d0274 100644 --- a/schemas/v1/_schemas_v1_media-buy_create-media-buy-request_json.json +++ b/schemas/v1/_schemas_v1_media-buy_create-media-buy-request_json.json @@ -32,11 +32,6 @@ "format": "date-time", "description": "Campaign end date/time in ISO 8601 format" }, - "budget": { - "type": "number", - "description": "Total budget for this media buy.
