A FastAPI-based MCP server that integrates with MCP tools and provides a chat interface with conversation management, streaming responses, and dynamic MCP server configuration
This MCP server has moderate definition quality with several critical gaps. Tool naming follows verb_noun conventions reasonably well (query, stream, list_conversations, get_conversation, create_conversation, delete_conversation, update_conversation_title, get_config, update_config, get_config_update_status). However, parameter schemas are incomplete and many lack proper type information. Descriptions are present but generic for many tools. The server exposes configuration management and conversation state operations, which are reasonable for an agent wrapper, but lacks rigor in parameter validation and error guidance. No tool annotations (readOnlyHint/destructiveHint) are visible despite clear semantic intent. Output schemas are not documented in the source code provided.
Create a new conversation
Delete a conversation by ID
Retrieve the current MCP server configuration
Check the status of a configuration update operation
Retrieve a specific conversation by ID
Retrieve all stored conversations
Process a user query with MCP tools and return a response
Tool annotations missing: No readOnlyHint, destructiveHint, or idempotentHint declarations visible. Tools like delete_conversation and update_config should be explicitly marked as destructive or non-idempotent to guide agent behavior.
Output schemas not documented in source code. Tool descriptions do not specify what fields clients should expect in responses (e.g., what does query() return beyond 'answer' and 'conversation_id'? What structure does list_conversations return?).
Parameter descriptions lack detail on constraints and formats. For example, 'conversation_id' is described as 'Optional conversation ID to maintain context' but does not specify format, length, or whether it must exist. 'history_turns' has no range constraints documented.

Stream responses for a user query with MCP tools using Server-Sent Events
Update the MCP server configuration and restart the agent
Update the title of a conversation
Error handling and recovery guidance absent. No documentation of what errors each tool can raise, whether they are retryable, or how the LLM should respond. For example, delete_conversation could fail if conversation does not exist, but the description provides no guidance.
Destructive operations lack confirmation/dry-run pattern. delete_conversation and update_config can permanently alter state but have no pre-flight validation or confirmation mechanism described.
Configuration update operation (update_config) accepts an arbitrary 'config' object with type 'object'. No schema validation, no description of valid structure, no examples. LLMs will likely hallucinate config structures, leading to failures.
Pagination not implemented for list_conversations. With unbounded conversation lists, LLM context can be exhausted. Tool lacks limit, offset/cursor, and total_count parameters.
