HireNimbus MCP Server
Model Context Protocol server that connects AI assistants (Claude, ChatGPT, Gemini) to the HireNimbus home-services marketplace. Enables provider search, review aggregation, homeowner profile retrieval, and job booking — all through natural conversation.
Architecture
- Runtime: Python 3.10, FastAPI, FastMCP (
mcp1.26.0) - Transport: Streamable HTTP at
/mcp(rewritten from/for root-level MCP clients) - Deploy: AWS Lambda (arm64) via SAM + Docker container image; Mangum ASGI adapter
- Auth: Optional OAuth2 with JWT Bearer tokens; rate limiting per IP
Quick Start
# 1. Local secrets (gitignored — never commit)
cp local.config.example.json local.config.json
# Edit local.config.json with your values (or use .env — see .env.example)
# 2. SAM deploy overrides (ECR image URI — gitignored)
cp samconfig.local.toml.example samconfig.local.toml
# Edit samconfig.local.toml with your AWS ECR repository
# Build & deploy to AWS (local)
sam build && sam deploy --config-file samconfig.toml --config-file samconfig.local.toml
# Local development
pip install -r requirements.txt
uvicorn src.main:app --reload
GitHub Actions auto-deploy on main uses repository secrets (see internal deploy docs).
Configuration
Sensitive values live in local.config.json (gitignored) or environment variables. Copy local.config.example.json → local.config.json and fill in your values. Env vars always take precedence.
Public defaults remain in code for shared HireNimbus API endpoints (service.hirenimbus.com). URLs, tokens, and credentials must be set explicitly.

Typical flow: The assistant retrieves pending invoices for the homeowner, presents line items and totals, and lets the homeowner approve, reject, or request changes — all conversationally.

Typical flow: After booking a job, the homeowner asks "Can I get this done Friday morning?" — the assistant checks provider availability and locks in a time slot, notifying both parties.
Typical Conversation Flow

User: "Tell me more about the first one"
-> get_provider_details(slug="...")
User: "What do people say about them?"
-> get_provider_reviews(slug="...")
User: "Book them for a leaking faucet"
-> get_homeowner_profile() # load saved name/phone/address
-> [confirm with user]
-> create_booking(...) # submit job + notify provider
User: "Schedule it for Friday morning"
-> schedule_appointment(...) # (planned)
User: "They sent an invoice — looks good, approve it"
