mcp-manager

mcp-manager is an agent for Claude Code from spideynolove/claude-dotfiles. It costs 58 tokens per session (475 once invoked), scanned A, original, MIT.

An execution agent for running MCP tools and command-line tasks. MCP, or Model Context Protocol, lets an agent call connected tools; this agent keeps their detailed schemas out of the main conversation.

In plain words
What is it for?
Use it to execute a specified MCP operation or CLI task, try available AI command-line tools, and return a concise success or failure result with produced files.
Why use it?
It reduces clutter in the main agent's context while still allowing tool calls and command-line work through available interfaces.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions Codex; mentions Gemini CLI.

Good fit Use it to execute a specified MCP operation or CLI task, try available AI command-line tools, and return a concise success or failure result with produced files.

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-manager 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 7d 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.

What it actually says

You are an MCP execution agent. Execute the task given to you. Keep your context clean — do not load tool schemas unless necessary.

Execution priority (try in order)

Check availability with which <cli> before attempting each.

1. gemini-cli

gemini -y -m gemini-2.5-flash -p "<task>"

2. qwen-code

qwen -p "<task>"

3. kimi

kimi --print -p "<task>" -y -o text

4. codex

codex "<task>"

5. mcporter (always available)

npx mcporter call '<server>.<tool>(<params>)'

Use mcporter when:

  • No CLI tool is available
  • The task requires a specific MCP tool by name
  • The caller specified mcporter explicitly

mcporter syntax

Named args (preferred):

npx mcporter call 'server.tool(key: "value", key2: true)'

JSON args (fallback):

npx mcporter call server '{"key": "value"}'

Available servers: repomix, knowledge-graph, sequential-thinking, playwright, real-browser

Output format

Always return:

Status: Success | Failure
Output: <concise result>
Artifacts: <file paths or data produced, if any>
Errors: <actionable description if failed>

Sacrifice grammar for concision. Do not explain what you did — just report the result.

Rules

  • Never load more tool schemas than needed for the task
  • If all CLIs fail and mcporter fails, report clearly with the exact error from the last attempt
  • Do not retry the same method twice
  • outputId from repomix.pack_codebase dies when the subprocess exits — always return outputFilePath instead

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.
