phonepe-pg-docs-mcp 1.0.2

MCP server that scrapes PhonePe Payment Gateway developer documentation and answers API integration questions

phonepe-pg-docs-mcp

PhonePe Payment Gateway — Documentation & Knowledge Base MCP

An MCP (Model Context Protocol) server published by PhonePe that gives any AI agent — Claude, GPT, Cursor, Copilot, Windsurf — instant access to PhonePe Payment Gateway developer documentation and a curated knowledge base.

Integrate PhonePe PG faster by letting your AI coding assistant answer questions directly from the official docs, without leaving your IDE.

No PhonePe credentials required. This MCP is entirely read-only.

---

Why use this?

When integrating PhonePe PG, developers commonly need to:

• Look up which API to call for a specific action
• Understand the request/response schema for an endpoint
• Check what order states exist and what each means
• Debug error codes like AUTHORIZATION_FAILED
• Find out if PhonePe supports a feature (recurring payments, international, EMI, etc.)
• Compare Standard Checkout vs Custom Checkout vs Payment Links

This MCP lets your AI agent answer all of these questions instantly — from a pre-indexed, always-up-to-date snapshot of the official developer docs — so you can stay in your editor and keep coding.

Example conversations

Once configured, talk to your AI agent naturally:

You: "Does PhonePe support recurring payments?"
MCP: ask_knowledge_base → Yes. UPI AutoPay and eNACH are supported.
     Requires the AutoPay permission to be enabled by PhonePe...

You: "What API do I call to generate a UPI QR for payment?"
MCP: ask_knowledge_base → POST /payments/v2/pay with paymentFlow.type = UPI_QR
     Doc: get_section_content('custom-checkout-v2/pay/upi-qr')

You: "Show me the full Custom Checkout UPI Intent integration steps"
MCP: get_section_content('custom-checkout-v2/pay/upi-intent') → full guide

You: "Find everything about webhook verification"
MCP: search_docs('webhook') → 10 matching sections in 2 ms

You: "What does AUTHORIZATION_FAILED mean?"
MCP: get_error_code_info → HTTP 401, expired token, re-fetch via /v1/oauth/token

You: "What are all the states a PhonePe payment order can be in?"
MCP: ask_knowledge_base → PENDING, COMPLETED, FAILED, CANCELLED + descriptions

You: "Which PhonePe products need special permission to use?"
MCP: list_products → Custom Checkout, AutoPay, Payment Links (each individually gated)

Adding or fixing documentation sections

The full list of indexed pages is in docs_registry.yml. To add a new page:

1. Add an entry under sections.public or sections.additional:

   my-new-section: /payment-gateway/path/to/page
   

2. Rebuild the local index:

   pip install httpx pyyaml beautifulsoup4
   python scripts/build_index.py
   

3. Verify with a search: search_docs("your new topic")
4. Open a pull request

Updating the curated knowledge base

Product descriptions, feature flags, FAQs, and error code explanations live in
src/phonepe_docs_mcp/knowledge/knowledge_base.yml. Edit that file directly — no code changes needed.

Running locally (development)

git clone https://github.com/PhonePe/phonepe-pg-docs-mcp.git
cd phonepe-pg-docs-mcp
pip install -e ".[test]"

# Build the doc index (required once before first run)
python scripts/build_index.py

# Run tests
pytest

# Start the MCP server
phonepe-pg-docs

Releasing a new version (maintainers)

1. Bump version in pyproject.toml
2. Add a changelog entry in CHANGELOG.md
3. Merge to main
4. Trigger the Manual Release to PyPI GitHub Actions workflow

The CI pipeline automatically:

1. Runs python scripts/build_index.py — re-indexes all 241 doc sections with the latest content
2. Bundles the fresh doc_index.db inside the wheel
3. Publishes to PyPI via twine

Every pip install phonepe-pg-docs-mcp always delivers the latest pre-indexed documentation snapshot.
