mcp-cli

mcp-cli is a skill for Claude Code, Codex from dhar174/custom_github_copilot_agent_builder. It costs 49 tokens per session (636 once invoked), scanned A, a copy of mcp-cli, MIT.

A command-line interface for Model Context Protocol servers, which connect an agent to external tools such as filesystems, databases, and APIs.

In plain words
What is it for?
Listing MCP servers, finding tools, viewing their input schemas, and executing tool calls with JSON arguments.
Why use it?
It lets you discover available tools, inspect the inputs they require, and call them from a terminal.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

mcp-cli 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 yesterday.

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.

Origin

This is a copy

100% identical to mcp-cli — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MCP-CLI

Access MCP servers through the command line. MCP enables interaction with external systems like GitHub, filesystems, databases, and APIs.

Commands

Command Output
mcp-cli List all servers and tool names
mcp-cli <server> Show tools with parameters
mcp-cli <server>/<tool> Get tool JSON schema
mcp-cli <server>/<tool> '<json>' Call tool with arguments
mcp-cli grep "<glob>" Search tools by name

Add -d to include descriptions (e.g., mcp-cli filesystem -d)

Workflow

  1. Discover: mcp-cli → see available servers and tools
  2. Explore: mcp-cli <server> → see tools with parameters
  3. Inspect: mcp-cli <server>/<tool> → get full JSON input schema
  4. Execute: mcp-cli <server>/<tool> '<json>' → run with arguments

Examples

# List all servers and tool names
mcp-cli

# See all tools with parameters
mcp-cli filesystem

# With descriptions (more verbose)
mcp-cli filesystem -d

# Get JSON schema for specific tool
mcp-cli filesystem/read_file

# Call the tool
mcp-cli filesystem/read_file '{"path": "./README.md"}'

# Search for tools
mcp-cli grep "*file*"

# JSON output for parsing
mcp-cli filesystem/read_file '{"path": "./README.md"}' --json

# Complex JSON with quotes (use heredoc or stdin)
mcp-cli server/tool <<EOF
{"content": "Text with 'quotes' inside"}
EOF

# Or pipe from a file/command
cat args.json | mcp-cli server/tool

# Find all TypeScript files and read the first one
mcp-cli filesystem/search_files '{"path": "src/", "pattern": "*.ts"}' --json | jq -r '.content[0].text' | head -1 | xargs -I {} sh -c 'mcp-cli filesystem/read_file "{\"path\": \"{}\"}"'

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.
