mcpscope AGENTS.md

A project instruction file for mcpscope, a tool that analyzes MCP servers and multi-step interactions with language models.

In plain words
What is it for?
Use it when developing mcpscope or inspecting its runtime analysis, data model, database, CLI, MCP interface, or tests.
Why use it?
It directs agents to the right documentation and emphasizes consistent behavior across the API, command line, MCP interface, and web interface.

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

mcpscope 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 2d 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.

mcpscope Agent Guide

This guide is for agents working on mcpscope's own code. If you are an agent (or configuring one) using mcpscope to test an MCP server, you want MCP.md and EXAMPLE.md instead — mcpscope speaks MCP itself.

mcpscope is a backend-centered runtime analysis tool for MCP and multi-turn LLM workflows. Optimize for correctness, inspectability, and parity across the backend API, CLI, MCP interface, and thin Svelte frontend.

Fast Start

Read only what the task needs:

  • README.md for the product overview and the Documentation index of every doc — start there if the right file isn't listed below; DEVELOPMENT.md for run-from-source and dev commands
  • ARCHITECTURE.md for runtime flow, persistence, execution, and adapters
  • DATA-MODEL.md for sessions, turns, rounds, parts, and canonical IDs
  • DATABASE-SCHEMA.md for the SQLite tables behind that model
  • TESTING.md for regression strategy and test selection
  • CLI.md and MCP.md for command and tool behavior
  • BENCHMARK.md for the benchmark suite/case/run feature, deterministic metrics, and LLM rubric evaluation — the latter is implemented as a benchmark_evaluation analysis workflow (one judge session per run-session), so it shares the analysis subsystem rather than being a separate engine; treat the two as one mechanism when changing either
  • PROVIDERS.md when touching reasoning, token counting, or context-window handling across LM Studio / Ollama / OpenRouter
  • DESIGN-SYSTEM.md before any frontend visual change — tokens, shared primitives, and patterns. Reuse the primitives; keep DESIGN-SYSTEM.md, frontend/src/app.css, and the live Design System Reference (DesignReference.svelte) in sync.

The docs above are references, not pre-read requirements. Keep context lean and open only the specific files needed for the task at hand.

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.
