Greptile Overview

Summary

Updated MCP server documentation to reflect recent changes in the mcp-server-browserbase package. Key changes include removing all multi-session functionality and documentation, updating model references to latest Claude 4.5 versions (Sonnet and Haiku), and adding the experimental get_url tool.

Major Changes:

• Removed multi-session management tools and architecture documentation from introduction.mdx and tools.mdx
• Updated Anthropic model names to claude-sonnet-4-5-20250929 and claude-haiku-4-5-20251001 across all docs
• Cleaned up OpenAI model list (removed o1/o3 models, added gpt-4.1)
• Fixed documentation link to point to correct models configuration page
• Simplified session management section to focus on single-session workflow

Issues Found:

• Documentation formatting inconsistency in models.mdx table (comma-separated model names)
• Incorrect parameter documentation for browserbase_stagehand_extract in tools.mdx (using ParamField for output instead of ResponseField)

Confidence Score: 4/5

• This PR is safe to merge after addressing minor documentation issues
• Documentation-only changes that correctly reflect MCP server updates. Two minor issues found: table formatting inconsistency and incorrect parameter type in API documentation. These don't affect functionality but should be fixed for accuracy.
• docs/integrations/mcp/tools.mdx has incorrect parameter documentation, docs/configuration/models.mdx has formatting inconsistency

syntax: instruction is an output parameter, not an input - this should be wrapped in a ResponseField not a ParamField

Suggested change

	<ParamField path="instruction" type="string">
	Extracted text content from the current page

	<ResponseField name="content" type="string">
