What is shodan-mcp-server AGENTS.md?

A connector that exposes Shodan, an internet-connected device and service search engine, as tools for a coding agent. It uses the Shodan API and can be run as a web service.

Searching Shodan and using its available device and service lookup tools, with configuration for the API key and server access.

It lets an agent query Shodan through defined tools instead of requiring custom API integration in each project.

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	$0.01189	$0.01189
Opus 5.5	$0.00476	$0.00476
Sonnet 5.5	$0.00238	$0.00238

Security

Grade A, and why

shodan-mcp-server AGENTS.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.

Agent Instructions for mcp-shodan-server

Project Overview

An MCP (Model Context Protocol) server that exposes the Shodan API as MCP tools. Built with FastMCP and the official shodan library.

Key Files

File	Purpose
`server.py`	Entry point — creates `FastMCP` app, initializes Shodan client via `init_client()`, wraps tool functions with `@mcp.tool()`, serves via HTTPS (uvicorn + Starlette)
`tools/shodan.py`	All 30 tool implementations as standalone functions + module-level `_client` singleton + `init_client()` factory
`requirements.txt`	Python dependencies (fastmcp, mcp, shodan, uvicorn, starlette)
`.env`	Environment config (`SHODAN_API_KEY`, `HOST_PORT`, `HOST_ADDRESS`, `SSL_CERTFILE`, `SSL_KEYFILE`, `CORS_ORIGINS`)
`Dockerfile` / `docker-compose.yml`	Container setup

 MCP decorators        ▶     Pure API logic
 (tool descriptions)         (no MCP dependency)

server.py: MCP layer — imports tools.shodan module + init_client(), defines @mcp.tool() wrappers that delegate to the tool functions
tools/shodan.py: API layer — standalone functions, module-level _client singleton, try/except error handling
tools/shodan.py has no MCP dependency (no from mcp.server import FastMCP)
All tools catch shodan.APIError and return {"error": str(e)} instead of raising
init_client(api_key) is called once at startup in server.py to set the module-level _client

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.
