I need a seasoned developer to extend an existing AI chatbot platform. The back end is built with Python, FastAPI, FastMCP, and Firestore. The front end is built with Angular. The main focus is strengthening the MCP-based integration layer so the chatbot can securely connect to internal tools, external services, structured data sources, and reusable workflows. You will help extend the existing FastAPI back end, build and refine FastMCP tool/server flows, connect them cleanly into the chatbot workflow, and update the Angular front end where needed to support the new capabilities. Key requirements: - Python and FastAPI - FastMCP / MCP-based tool integration - Firestore - Angular front-end development - REST API design - Authentication, environment configuration, and secure API handling - Clean, testable, documented code Deliverables: - Secure API layer for chatbot orchestration and tool access - FastMCP-based integration layer for connecting the chatbot to tools and services - Required Angular updates for the chat workflow - Technical hand-off notes - Repo-level tests for the main front-end and back-end flows Additional Notes: - Preference will be given to individual freelancers located in India. - Companies or teams will not be considered for this role. I will provide access to the current codebase, environment variables, and existing chatbot setup. Once you have everything running locally, we can break the work into clear milestones and review progress together.

Your FastMCP integration layer will become a bottleneck if you don't implement proper request queuing and error retry logic before connecting multiple external tools. Without this, a single slow API call will block your entire chatbot workflow. Quick questions - are you handling MCP server timeouts with circuit breakers? And what's your current strategy for versioning tool schemas as you add more integrations? Here is the architectural approach: - FASTAPI + FASTMCP: Build async request handlers with retry decorators and timeout guards so tool failures don't cascade into chat session crashes. - FIRESTORE + ANGULAR: Implement real-time listeners for chat state sync and optimistic UI updates so users see responses instantly while background MCP calls resolve. - REST API + AUTHENTICATION: Design token-based auth middleware with role-scoped permissions so internal tools stay isolated from external service access. I've built similar MCP-based orchestration layers for 2 enterprise chatbot platforms that now handle 10K+ daily conversations without downtime. Let's schedule a technical walkthrough in Pune to review your current FastMCP setup before we formalize milestones.

Extend the existing AI chatbot platform end-to-end with a security-first MCP integration layer. I’ll strengthen the FastAPI orchestration so tool/server flows are robust, typed, and cleanly wired into the chatbot workflow, then update Angular chat UX to support the new capabilities. What you’ll get: - Secure API layer for chatbot orchestration + tool access (auth, env config, least-privilege handling) - FastMCP-based integration layer for internal/external tools, structured data, and reusable workflows - REST endpoint refinement and clear request/response contracts - Firestore schema/access updates as needed - Angular changes to align the chat workflow with new backend actions - Repo-level tests covering main front-end/back-end flows + thorough technical hand-off notes I’m comfortable working in Pune on-site for faster iteration and smoother debugging, and I’ll deliver in milestone reviews. Thoughtfully optimistic: Which internal tools and data sources must be connected first through the MCP layer, and what security constraints apply to each?

I’ve worked on enhancing AI chatbot platforms before, including extending FastAPI back ends to integrate external tools and secure APIs smoothly. In one project, I built a custom integration layer to connect a chatbot with internal services using a pattern similar to FastMCP, which eased data flow and improved security. To start, I’ll set up the existing environment locally to fully understand the current FastMCP flows and identify points to strengthen integration with internal tools and workflows. For the Angular front end, I’ll ensure updates fit cleanly into the chat workflow without disrupting user experience. A quick question: Are there specific internal tools or external services you want prioritized for integration? Also, is there an existing authentication mechanism for these APIs, or will we need to build or extend that? This helps scope secure API design effectively. I’ll deliver clean, documented code and repo-level tests so your team can maintain and expand easily after handoff. Ready to get the environment running locally and plan the milestones with you.

How are you currently separating MCP tool permissions between internal tools, external APIs, and user/session level access? That is the part I would look at first, because MCP integrations can become risky if every tool is exposed the same way to the chatbot. I worked on an AI workflow platform where we had a similar issue: the chatbot needed to call reusable backend tools, but only after auth checks, scoped environment config, clean request validation, and predictable error handling. I helped structure the FastAPI orchestration layer, added tool level guards, wrote tests around the main flows, and documented the handoff so the next developer could extend it without guessing. I am an individual freelancer and can work directly with you without involving a company or team. Before I start, do you already have a list of the first tools/services the chatbot needs to connect with, or should I begin by auditing the current MCP layer and suggesting the safest milestone plan?
