Perplexica MCP Server

**User:** <task> Given the following description of the arguments of the search endpoint of the perplexica server, make our MCP server working correctly: Request Parameters chatModel (object, optional): Defines the chat model to be used for the query. For model details you can send a GET request at http://localhost:3000/api/models. Make sure to use the key value (For example "gpt-4o-mini" instead of the display name "GPT 4 omni mini"). provider: Specifies the provider for the chat model (e.g., openai, ollama). name: The specific model from the chosen provider (e.g., gpt-4o-mini). Optional fields for custom OpenAI configuration: customOpenAIBaseURL: If you’re using a custom OpenAI instance, provide the base URL. customOpenAIKey: The API key for a custom OpenAI instance. embeddingModel (object, optional): Defines the embedding model for similarity-based searching. For model details you can send a GET request at http://localhost:3000/api/models. Make sure to use the key value (For example "text-embedding-3-large" instead of the display name "Text Embedding 3 Large"). provider: The provider for the embedding model (e.g., openai). name: The specific embedding model (e.g., text-embedding-3-large). focusMode (string, required): Specifies which focus mode to use. Available modes: webSearch, academicSearch, writingAssistant, wolframAlphaSearch, youtubeSearch, redditSearch. optimizationMode (string, optional): Specifies the optimization mode to control the balance between performance and quality. Available modes: speed: Prioritize speed and return the fastest answer. balanced: Provide a balanced answer with good speed and reasonable quality. query (string, required): The search query or question. systemInstructions (string, optional): Custom instructions provided by the user to guide the AI's response. These instructions are treated as user preferences and have lower priority than the system's core instructions. For example, you can specify a particular writing style, format, or focus area. history (array, optional): An array of message pairs representing the conversation history. Each pair consists of a role (either 'human' or 'assistant') and the message content. This allows the system to use the context of the conversation to refine results. Example: [ ["human", "What is Perplexica?"], ["assistant", "Perplexica is an AI-powered search engine..."] ] stream (boolean, optional): When set to true, enables streaming responses. Default is false. </task> <environment_details> # VSCode Visible Files perplexica_mcp_tool.py # VSCode Open Tabs perplexica_mcp_tool.py,test_search.py # Current Time 30.5.2025, 10:48:02 PM (Europe/Berlin, UTC+2:00) # Current Context Size (Tokens) (Not available) # Current Cost $0.00 # Current Mode <slug>code</slug> <name>💻 Code</name> <model>anthropic/claude-sonnet-4-20250514</model> # Current Workspace Directory (/Users/the/Developer/thetom42/github/perplexica-mcp) Files perplexica_mcp_tool.py pyproject.toml test_search.py uv.lock </environment_details> --- **Assistant:** I'll examine the current MCP server implementation and update it to correctly handle all the parameters described in the Perplexica search endpoint documentation. <thinking> Let me first read the current implementation to understand what needs to be fixed or updated. </thinking> <read_file> <path>perplexica_mcp_tool.py</path> </read_file> Now let me examine the test file to understan [Response interrupted by a tool use result.

This ensures that when you configure the MCP server in Claude, each parameter will display its description. **Key Changes Made:** 1. **Added Import:** Added `from typing import Annotated` to support annotated type hints 2. **Updated Function Signature:** Replaced simple type hints with `Annotated` types that include descriptions: - `query`: "The search query or question" - `focus_mode`: "Focus mode, must be one of: 'webSearch', 'academicSearch', 'writingAssistant', 'wolframAlphaSearch', 'youtubeSearch', 'redditSearch'" - `chat_model`: "Chat model configuration with provider (e.g., openai, ollama), name (e.g., gpt-4o-mini), and optional customOpenAIBaseURL and customOpenAIKey" - `embedding_model`: "Embedding model configuration with provider (e.g., openai) and name (e.g., text-embedding-3-large)" - `optimization_mode`: "Optimization mode: 'speed' (prioritize speed) or 'balanced' (balance speed and quality)" - `history`: "Conversation history as list of [role, message] pairs where role is 'human' or 'assistant'" - `system_instructions`: "Custom instructions to guide the AI's response style, format, or focus area" - `stream`: "Whether to stream responses (default: False)" Now when you configure the Perplexica MCP server in Claude, each parameter will show its proper description, making it much easier to understand how to use each parameter correctly. The MCP framework will automatically extract these descriptions from the `Annotated` type hints and include them in the tool schema. </result> </attempt_completion> --- **User:** [attempt_completion] Result: The user has provided feedback on the results.

Here are the key changes made: **Major Changes:** 1. **Added Pydantic Dependencies:** - Added `pydantic` to the script dependencies - Imported `BaseModel`, `Field` from Pydantic - Added proper typing imports (`Optional`, `List`, `Dict`, `Any`) 2. **Created SearchRequest Pydantic Model:** - Defined a [`SearchRequest`](perplexica_mcp_tool.py:19) class that inherits from `BaseModel` - Each field uses `Field()` with explicit descriptions: - `query`: "The search query or question" - `focus_mode`: "Focus mode, must be one of: 'webSearch', 'academicSearch', 'writingAssistant', 'wolframAlphaSearch', 'youtubeSearch', 'redditSearch'" - `chat_model`: "Chat model configuration with provider (e.g., openai, ollama), name (e.g., gpt-4o-mini), and optional customOpenAIBaseURL and customOpenAIKey" - `embedding_model`: "Embedding model configuration with provider (e.g., openai) and name (e.g., text-embedding-3-large)" - `optimization_mode`: "Optimization mode: 'speed' (prioritize speed) or 'balanced' (balance speed and quality)" - `history`: "Conversation history as list of [role, message] pairs where role is 'human' or 'assistant'" - `system_instructions`: "Custom instructions to guide the AI's response style, format, or focus area" - `stream`: "Whether to stream responses (default: False)" 3. **Updated Function Signature:** - Changed the [`search()`](perplexica_mcp_tool.py:30) function to accept a single `SearchRequest` parameter - Updated the function body to access fields via `request.field_name` 4. **Proper Type Annotations:** - Used `Optional[Type]` for optional parameters - Used specific types like `List[List[str]]` for history - Used `Dict[str, Any]` for model configurations This Pydantic-based approach should properly expose parameter descriptions in the MCP tool schema, making them visible when you configure the server in Claude. The FastMCP framework should automatically extract the field descriptions from the Pydantic model and include them in the tool's JSON schema. </result> </attempt_completion> --- **User:** [attempt_completion] Result: The user has provided feedback on the results.

The key changes made: **Updated Approach:** 1. **Enhanced Tool Decorator:** Used the [`@mcp.tool()`](perplexica_mcp_tool.py:18) decorator with explicit `name` and `description` parameters 2. **Proper Type Annotations:** Used standard Python typing with: - `Optional[Dict[str, Any]]` for optional dictionary parameters - `Optional[List[List[str]]]` for the history parameter - `Optional[str]` for optional string parameters - `bool` for the stream parameter 3. **Detailed Docstring:** Added comprehensive parameter descriptions in the docstring using the standard Args format: - `query`: The search query or question - `focus_mode`: Focus mode, must be one of: 'webSearch', 'academicSearch', 'writingAssistant', 'wolframAlphaSearch', 'youtubeSearch', 'redditSearch' - `chat_model`: Chat model configuration with provider, name, and optional custom OpenAI settings - `embedding_model`: Embedding model configuration with provider and name - `optimization_mode`: Optimization mode ('speed' or 'balanced') - `history`: Conversation history as list of [role, message] pairs - `system_instructions`: Custom instructions to guide AI response - `stream`: Whether to stream responses 4. **Maintained Functionality:** The core functionality remains the same - all parameters are correctly passed to the [`perplexica_search()`](perplexica_mcp_tool.py:48) function and properly mapped to the Perplexica API. This approach uses FastMCP's standard parameter description mechanism through docstrings and proper type annotations, which should be recognized by the MCP framework and displayed in Claude's interface. The tool maintains full compatibility with the Perplexica API while providing clear parameter descriptions. </result> </attempt_completion>
