sn-mcp-server: Instructions file for GitHub Copilot

.github/copilot-instructions.md

sn-mcp-server copilot-instructions.md is an instructions file for GitHub Copilot from signnow/sn-mcp-server. It costs 555 tokens per session, scanned A, original, MIT.

Project-specific instructions for developing sn-mcp-server, a Python server and client library that connects software to SignNow’s electronic-signature API.

In plain words
What is it for?
Building and installing the project, running its tests, adding SignNow integrations, working with API data models, and using Docker-based development workflows.
Why use it?
They give an AI coding agent the repository layout, development conventions, build commands, testing steps, and integration patterns it needs to work consistently.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is signnow/sn-mcp-server's own configuration. It tells GitHub Copilot how to work on sn-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything sn-mcp-server configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sn-mcp-server copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Copilot Instructions for AI Coding Agents

Project Overview

  • This project is a Python-based server and client SDK for SignNow API integration, organized under src/.
  • Major components:
    • sn_mcp_server/: Main server logic, CLI, authentication, and tool integrations.
    • signnow_client/: Handles SignNow API communication, models, and utility functions.
    • examples/: Usage examples for different frameworks (LangChain, LlamaIndex, SmolAgents).
    • tests/: Unit tests, organized by module.

Key Workflows

  • Build & Install: Use pip install . or python -m build from the project root.
  • Testing: Run pytest or python run_tests.py to execute all tests. Test modules are under tests/unit/.
  • Development: Main code is in src/. Use the Makefile for common tasks if present.
  • Docker: Use docker-compose.yml and Dockerfile for containerized development and deployment.

Project Conventions

  • All source code is under src/ (not the project root).
  • Each tool in sn_mcp_server/tools/ is a self-contained integration for a specific SignNow feature.
  • Models for API payloads are in signnow_client/models/.
  • Configuration is handled via config.py in each main package.
  • Use pyproject.toml for dependency and build management.

Integration & Patterns

  • The server (sn_mcp_server/server.py) loads tools dynamically from sn_mcp_server/tools/.
  • Authentication logic is in sn_mcp_server/auth.py and sn_mcp_server/token_provider.py.
  • Client logic for SignNow API is abstracted in signnow_client/client.py and submodules.
  • Example scripts demonstrate integration patterns for external frameworks.

Examples

  • To add a new tool, create a module in sn_mcp_server/tools/ and register it in sn_mcp_server/app.py.
  • To extend API models, add to signnow_client/models/ and update relevant client methods.

Testing

  • Place new tests in tests/unit/ mirroring the source structure.
  • Run all tests with pytest or python run_tests.py.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
