To do this effectively, I should: 1. First, read the current README.md to understand what it currently says 2. Read the CHANGELOG.md to see what version 0.2.0 included and understand the format 3. Examine the current implementation to understand what has changed since 0.2.0 4. Update the README.md to reflect the current state 5. Add version 0.3.0 to the CHANGELOG.md with the new changes Let me start by reading the current README.md file. </thinking> I'll help you adapt the README.md to the current implementation state and add version 0.3.0 to the CHANGELOG.md. Let me start by examining the current files to understand what needs to be updated. <read_file> <args> <file> <path>README.md</path> </file> </args> </read_file> <read_file> <args> <file> [Response interrupted by a tool use result.

Previous Conversation: The conversation began with a task to adapt the README.md to the current state of implementation and add version 0.3.0 to the CHANGELOG.md. The user then requested creating a GitHub issue to document these changes, which led to some technical difficulties with the GitHub MCP server permissions. After providing the issue content in a proper GitHub issue format, the conversation was interrupted and resumed with a question about adding Docker information to the README.md. ### 2. Current Work: I was in the process of updating the README.md to include Docker deployment options. The user noticed that while the project has Docker files (Dockerfile, docker-compose.yml, docker-compose-sse.yml), the README.md doesn't mention Docker deployment options. I had just started reading the current README.md content and was about to examine the Docker Compose files to understand the available deployment options before adding a comprehensive Docker section to the documentation. ### 3. Key Technical Concepts: - **FastMCP Framework**: Modern MCP server framework with built-in transport support - **Multiple Transport Support**: stdio, SSE (Server-Sent Events), and Streamable HTTP transports - **Model Context Protocol (MCP)**: Protocol for AI assistant integration - **Perplexica Integration**: AI-powered search engine backend - **Docker Containerization**: Container deployment with security best practices - **Environment Configuration**: Using .env files for configuration management - **Version Management**: Semantic versioning with changelog documentation ### 4. Relevant Files and Code: - **README.md**: - Updated to reflect FastMCP-based architecture - Contains installation, configuration, and usage instructions - Missing Docker deployment section - **CHANGELOG.md**: - Added comprehensive version 0.3.0 entry documenting FastMCP migration - Documents architectural changes and improvements - **pyproject.toml**: - Updated to version 0.3.0 - Removed FastAPI dependency, streamlined for FastMCP - **Dockerfile**: - Fixed command arguments to match current implementation - Uses Python 3.13 Alpine with security best practices - **docker-compose.yml** and **docker-compose-sse.yml**: - Available but not yet examined for documentation purposes - **src/perplexica_mcp.py**: - FastMCP-based implementation with unified transport handling - Environment variable: PERPLEXICA_BACKEND_URL ### 5. Problem Solving: Successfully completed the main documentation updates for version 0.3.0, including README.md adaptation and CHANGELOG.md updates. Encountered GitHub MCP server permissions issues when trying to create the issue automatically, but provided the user with properly formatted issue content for manual creation. The issue content was refined from changelog-style to proper GitHub issue format based on user feedback. ### 6. Pending Tasks and Next Steps: - **Add Docker Section to README.md**: Need to examine the Docker Compose files and add comprehensive Docker deployment instructions to the README.md - **Next Steps**: 1. Read docker-compose.yml and docker-compose-sse.yml to understand deployment options 2. Add a "Docker Deployment" section to README.md with: - Docker build instructions - Docker Compose usage examples - Environment variable configuration for containers - Port mapping and networking information - Production deployment considerations The user's most recent question was: "Should we add information about the docker option in the README.md?" - confirming that Docker documentation should be added to complete the documentation updates. --- **User:** [read_file for 'docker-compose.yml'.

Now I can see the complete structure of the README.md. I'll add a comprehensive Docker section after the "Usage" section and before the "Available Tools" section. This placement makes sense as it provides an alternative deployment method right after the basic usage instructions. <apply_diff> <path>README.md</path> <diff> <<<<<<< SEARCH :start_line:54 ------- ``` ## Available Tools ======= ``` ## Docker Deployment The server includes Docker support with multiple transport configurations for containerized deployments. ### Prerequisites - Docker and Docker Compose installed - External Docker network named `backend` (for integration with Perplexica) ### Create External Network ```bash docker network create backend ``` ### Build and Run #### Option 1: HTTP Transport (Streamable HTTP) ```bash # Build and run with HTTP transport docker-compose up -d # Or build first, then run docker-compose build docker-compose up -d ``` #### Option 2: SSE Transport (Server-Sent Events) ```bash # Build and run with SSE transport docker-compose -f docker-compose-sse.yml up -d # Or build first, then run docker-compose -f docker-compose-sse.yml build docker-compose -f docker-compose-sse.yml up -d ``` ### Environment Configuration Both Docker configurations support environment variables: ```bash # Create .env file for Docker cat > .env << EOF PERPLEXICA_BACKEND_URL=http://perplexica-app:3000/api/search EOF # Uncomment env_file in docker-compose.yml to use .env file ``` Or set environment variables directly in the compose file: ```yaml environment: - PERPLEXICA_BACKEND_URL=http://your-perplexica-host:3000/api/search ``` ### Container Details | Transport | Container Name | Port | Endpoint | Health Check | |-----------|----------------|------|----------|--------------| | HTTP | `perplexica-mcp-http` | 3001 | `/mcp/` | MCP initialize request | | SSE | `perplexica-mcp-sse` | 3001 | `/sse` | SSE endpoint check | ### Health Monitoring Both containers include health checks: ```bash # Check container health docker ps docker-compose ps # View health check logs docker logs perplexica-mcp-http docker logs perplexica-mcp-sse ``` ### Integration with Perplexica The Docker setup assumes Perplexica is running in the same Docker network: ```yaml # Example Perplexica service in the same compose file services: perplexica-app: # ... your Perplexica configuration networks: - backend perplexica-mcp: # ... MCP server configuration environment: - PERPLEXICA_BACKEND_URL=http://perplexica-app:3000/api/search networks: - backend ``` ### Production Considerations - Both containers use `restart: unless-stopped` for reliability - Health checks ensure service availability - External network allows integration with existing Perplexica deployments - Security best practices implemented in Dockerfile ## Available Tools >>>>>>> REPLACE </diff> </apply_diff> --- **User:** [apply_diff for 'README.md'] Result: <file_write_result> <path>README.md</path> <operation>modified</operation> <notice> <i>You do not need to re-read the file, as you have seen all changes</i> <i>Proceed with the task using these changes as the new baseline.</i> </notice> </file_write_result> <environment_details> # VSCode Visible Files README.md # VSCode Open Tabs README.md # Current Time 5.6.2025, 7:21:13 AM (Europe/Berlin, UTC+2:00) # Current Context Size (Tokens) 83.786 (42%) # Current Cost $1.27 # Current Mode <slug>code</slug> <name>💻 Code</name> <model>anthropic/claude-sonnet-4-20250514</model> </environment_details> --- **Assistant:** <attempt_completion> <result> I've successfully added a comprehensive Docker deployment section to the README.md. The new section includes: **Key Docker Features Added:** - **Prerequisites**: Docker, Docker Compose, and external network setup - **Two Transport Options**: HTTP and SSE with separate docker-compose files - **Environment Configuration**: Both .env file and direct environment variable approaches - **Container Details Table**: Clear overview of container names, ports, endpoints, and health checks - **Health Monitoring**: Instructions for checking container status and logs - **Perplexica Integration**: Example of how to integrate with existing Perplexica deployments - **Production Considerations**: Security and reliability features **Docker Deployment Options:** 1. **HTTP Transport** (`docker-compose.yml`): Streamable HTTP on port 3001 at `/mcp/` endpoint 2. **SSE Transport** (`docker-compose-sse.yml`): Server-Sent Events on port 3001 at `/sse` endpoint **Key Benefits:** - Both containers include health checks for monitoring - External network support for integration with existing Perplexica deployments - Restart policies for production reliability - Clear environment variable configuration options - Security best practices from the Dockerfile The Docker section is strategically placed after the basic usage instructions and before the tools documentation, providing users with a complete deployment alternative right after learning about the basic functionality. This completes the documentation updates for version 0.3.0, making the project fully documented for both local development and containerized production deployments. </result> </attempt_completion> --- **User:** [TASK RESUMPTION] This task was interrupted 3 minutes ago. It may or may not be complete, so please reassess the task context. Be aware that the project state may have changed since then.

I can see that there are MCP client configuration examples in the config directory, but there's no section in the README.md that explains how to configure MCP clients. This is an important gap since users need to know how to connect their MCP clients to the server. Let me add a comprehensive "MCP Client Configuration" section to the README.md. I'll place it after the "Available Tools" section and before the "Testing" section: <apply_diff> <path>README.md</path> <diff> <<<<<<< SEARCH :start_line:179 ------- - `stream` (boolean, optional): Whether to stream responses ## Testing ======= - `stream` (boolean, optional): Whether to stream responses ## MCP Client Configuration To use this server with MCP clients, you need to configure the client to connect to the Perplexica MCP server. Below are configuration examples for popular MCP clients. ### Claude Desktop #### Stdio Transport (Recommended) Add the following to your Claude Desktop configuration file: **Location**: `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows) ```json { "mcpServers": { "perplexica": { "command": "uv", "args": ["run", "/path/to/perplexica-mcp/src/perplexica_mcp.py", "stdio"], "env": { "PERPLEXICA_BACKEND_URL": "http://localhost:3000/api/search" } } } } ``` #### SSE Transport For SSE transport, first start the server: ```bash uv run src/perplexica_mcp.py sse ``` Then configure Claude Desktop: ```json { "mcpServers": { "perplexica": { "url": "http://localhost:3001/sse" } } } ``` ### Cursor IDE Add to your Cursor MCP configuration: ```json { "servers": { "perplexica": { "command": "uv", "args": ["run", "/path/to/perplexica-mcp/src/perplexica_mcp.py", "stdio"], "env": { "PERPLEXICA_BACKEND_URL": "http://localhost:3000/api/search" } } } } ``` ### Generic MCP Client For any MCP client supporting stdio transport: ```bash # Command to run the server uv run /path/to/perplexica-mcp/src/perplexica_mcp.py stdio # Environment variables PERPLEXICA_BACKEND_URL=http://localhost:3000/api/search ``` For HTTP/SSE transport clients: ```bash # Start the server uv run /path/to/perplexica-mcp/src/perplexica_mcp.py sse # or 'http' # Connect to endpoints SSE: http://localhost:3001/sse HTTP: http://localhost:3002/mcp/ ``` ### Configuration Notes 1. **Path Configuration**: Replace `/path/to/perplexica-mcp/` with the actual path to your installation 2. **Perplexica URL**: Ensure `PERPLEXICA_BACKEND_URL` points to your running Perplexica instance 3. **Transport Selection**: - Use **stdio** for most MCP clients (Claude Desktop, Cursor) - Use **SSE** for web-based clients or real-time applications - Use **HTTP** for REST API integrations 4. **Dependencies**: Ensure `uv` is installed and available in your PATH ### Troubleshooting - **Server not starting**: Check that `uv` is installed and the path is correct - **Connection refused**: Verify Perplexica is running and accessible at the configured URL - **Permission errors**: Ensure the MCP client has permission to execute the server command - **Environment variables**: Check that `PERPLEXICA_BACKEND_URL` is properly set ## Testing >>>>>>> REPLACE </diff> </apply_diff> --- **User:** [apply_diff for 'README.md'] Result: <file_write_result> <path>README.md</path> <operation>modified</operation> <notice> <i>You do not need to re-read the file, as you have seen all changes</i> <i>Proceed with the task using these changes as the new baseline.</i> </notice> </file_write_result> <environment_details> # VSCode Visible Files README.md # VSCode Open Tabs README.md # Current Time 5.6.2025, 7:25:52 AM (Europe/Berlin, UTC+2:00) # Current Context Size (Tokens) 96.171 (48%) # Current Cost $1.37 # Current Mode <slug>code</slug> <name>💻 Code</name> <model>anthropic/claude-sonnet-4-20250514</model> </environment_details> --- **Assistant:** <attempt_completion> <result> I've added a comprehensive "MCP Client Configuration" section to the README.md. The new section includes: **Key Features Added:** - **Claude Desktop Configuration**: Both stdio and SSE transport examples with file locations for macOS and Windows - **Cursor IDE Configuration**: Specific configuration format for Cursor's MCP integration - **Generic MCP Client**: Instructions for any MCP client supporting stdio, HTTP, or SSE transports - **Configuration Notes**: Important details about path configuration, Perplexica URL setup, transport selection, and dependencies - **Troubleshooting**: Common issues and solutions for MCP client setup **Configuration Examples Provided:** 1. **Claude Desktop (Stdio)**: JSON configuration with proper file paths and environment variables 2. **Claude Desktop (SSE)**: URL-based configuration for SSE transport 3. **Cursor IDE**: Server configuration format specific to Cursor 4. **Generic Clients**: Command-line examples and endpoint URLs **Transport Guidance:** - **Stdio**: Recommended for most MCP clients (Claude Desktop, Cursor) - **SSE**: For web-based clients or real-time applications - **HTTP**: For REST API integrations The section is strategically placed after the "Available Tools" section and before "Testing", providing users with complete setup instructions after learning about the server's capabilities. This addresses the gap in client-side configuration documentation and makes the project more accessible to users who want to integrate the Perplexica MCP server with their preferred MCP clients. </result> </attempt_completion>
