What is mcp-client-cli AGENTS.md?

Repository instructions for mcp-client-cli, a terminal program that lets users send prompts to language models and connect them to external tools. It also describes the project structure and how conversations and saved context work.

Use it when changing the command-line interface, model-provider support, tool connections, conversation saving, prompt templates, image input, or memory storage.

It helps a coding agent understand the command flow, supported model providers, tool connections, and where the main parts of the program live.

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

Security

Grade A, and why

mcp-client-cli 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.

Project Overview

mcp-client-cli is a CLI tool that acts as a Model Context Protocol (MCP) client. It allows users to run LLM prompts from the terminal with access to MCP-compatible servers/tools. The CLI supports multiple LLM providers (OpenAI, Anthropic, Google) and can be extended with any MCP-compatible server.

Key Features:

MCP client implementation for tool usage
Multi-provider LLM support (OpenAI, Anthropic, Google, local models)
Conversation persistence and continuation
Prompt templates
Image input support (via stdin or clipboard)
Memory storage for context across sessions

Architecture

The project uses:

LangChain/LangGraph: For LLM orchestration and agent execution
MCP SDK: For communicating with MCP servers
SQLite: For conversation checkpointing and memory storage
Rich: For terminal output formatting

Core Flow

User provides a query via CLI
cli.py parses arguments and loads configuration
MCP servers are initialized and tools are loaded
A LangGraph ReAct agent processes the query with available tools
Results are streamed back to the user with Rich formatting

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.
