you-contents extracts full page content from URLs via You.com’s remote MCP server. It supports markdown, HTML, and metadata formats and handles multiple URLs in a single request.
you-contents cannot be used via the DSL path (mcps=[]). crewAI’s _json_type_to_python maps all "array" types to bare list, which Pydantic v2 generates as {"items": {}} — a schema that OpenAI rejects. You must use MCPServerAdapter with the schema patching helpers below.
you-contents is not available on the free tier (?profile=free). An API key is required.
Installation
# MCPServerAdapter is required for you-contents
pip install "crewai-tools[mcp]>=0.1"

Parameters
| Parameter | Required | Type | Description |
|---|
urls | Yes | array[string] | URLs to extract content from (e.g., ["https://example.com"]) |
formats | No | array[string] | Output formats: "markdown", "html", "metadata" |
crawl_timeout | No | integer | Timeout in seconds (1–60) for page crawling |
| Format | Best for |
|---|
markdown | Text extraction, readability, LLM consumption |
html | Layout preservation, interactive content, visual fidelity |
metadata | Structured page information (site name, favicon, OpenGraph data) |
Example
Schema patching is required — mcpadapt generates invalid JSON Schema fields (anyOf: [], enum: null) that OpenAI rejects. The helpers below clean these schemas:
from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
import os
from typing import Any
def _fix_property(prop: dict) -> dict | None:
cleaned = {
k: v for k, v in prop.items()
if not (
(k == "anyOf" and v == [])
or (k in ("enum", "items") and v is None)
or (k == "properties" and v == {})
or (k == "title" and v == "")
)
}
if "type" in cleaned:
return cleaned
if "enum" in cleaned and cleaned["enum"]:
vals = cleaned["enum"]
if all(isinstance(e, str) for e in vals):
cleaned["type"] = "string"
return cleaned
if all(isinstance(e, (int, float)) for e in vals):
cleaned["type"] = "number"
return cleaned
if "items" in cleaned:
cleaned["type"] = "array"
return cleaned
return None
def _clean_tool_schema(schema: Any) -> Any:
if not isinstance(schema, dict):
return schema
if "properties" in schema and isinstance(schema["properties"], dict):
fixed: dict[str, Any] = {}
for name, prop in schema["properties"].items():
result = _fix_property(prop) if isinstance(prop, dict) else prop
if result is not None:
fixed[name] = result
return {**schema, "properties": fixed}
return schema
def _patch_tool_schema(tool: Any) -> Any:
if not (hasattr(tool, "args_schema") and tool.args_schema):
return tool
fixed = _clean_tool_schema(tool.args_schema.model_json_schema())

@classmethod
def model_json_schema(cls, *args: Any, **kwargs: Any) -> dict:
return fixed
PatchedSchema.__name__ = tool.args_schema.__name__

with MCPServerAdapter(server_params) as tools:

Combining with you-search
A common pattern: search with you-search via DSL, then extract content with you-contents via MCPServerAdapter. See You.com Search & Research Tools for search configuration.

Security
you-contents is higher risk for indirect prompt injection than search tools — it returns full page HTML/Markdown from arbitrary URLs. Always include the trust boundary in the agent’s backstory and never pass user-supplied URLs directly without validation. See MCP Security for full details.
