What is multiapimcpserver copilot-instructions.md?

Project instructions for a Python server that creates Model Context Protocol tools from OpenAPI specifications. OpenAPI is a machine-readable description of a web API, and MCP lets an assistant call tools exposed by a server.

Use them when working on the FastMCP OpenAPI project, including its parser, server, CLI, authentication, generated tools, or tests.

They give an agent the project's intended architecture, completed status, supported authentication methods, and rules for handling multiple APIs and parameters.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00520	$0.00520
Opus 5.5	$0.00208	$0.00208
Sonnet 5.5	$0.00104	$0.00104

Security

Grade A, and why

multiapimcpserver 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 2mo 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.

FastMCP OpenAPI Project Instructions

This project is a FastMCP wrapper that dynamically generates MCP (Model Context Protocol) tools from OpenAPI specifications.

Project Status: ✅ COMPLETE

All development tasks have been completed successfully:

✅ Project scaffolded with proper Python package structure
✅ Core functionality implemented (OpenAPI parsing, tool generation, MCP server)
✅ CLI interface created with multiple OpenAPI spec support
✅ Authentication support (Bearer, API Key, Basic Auth)
✅ Real MCP framework integration verified
✅ Parameter schema issues resolved (kwargs → proper function signatures)
✅ Testing infrastructure set up
✅ Documentation completed

Project Overview

Purpose: Enable AI assistants to interact with any REST API by automatically generating MCP tools from OpenAPI/Swagger specifications.

Key Features:

Dynamic tool generation from OpenAPI specs
Type-safe parameter validation
Multiple authentication methods
Support for multiple APIs in one server
CLI and programmatic interfaces

Architecture

src/fastmcp_openapi/server.py - Main MCP server implementation
src/fastmcp_openapi/parser.py - OpenAPI specification parser
src/fastmcp_openapi/tool_generator.py - Converts OpenAPI operations to MCP tools
src/fastmcp_openapi/client.py - HTTP client for API calls
src/fastmcp_openapi/models.py - Data models
src/fastmcp_openapi/config.py - Configuration models

Usage

# Basic usage
fastmcp-openapi --spec https://petstore.swagger.io/v2/swagger.json

# With authentication
fastmcp-openapi --spec https://api.example.com/openapi.json --auth-header "Bearer token"

# Multiple APIs
fastmcp-openapi --spec api1.json --spec api2.json --spec api3.json

# Test with MCP Inspector
npx @modelcontextprotocol/inspector fastmcp-openapi --spec examples/simple_api.json

Development Guidelines

Keep code clean and well-documented
Follow Python type hints and Pydantic models
Test with both local and remote OpenAPI specifications
Ensure proper error handling and logging
Maintain compatibility with MCP protocol standards

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.
