A project skill for managing Model Context Protocol (MCP) servers, which let an assistant use tools provided by other programs. It can list configured servers, check tool availability, show invocation formats, or add a server.

It helps inspect MCP servers, check required command-line tools, add servers, and find the correct tool-call names.

It keeps MCP setup and tool usage in one place instead of requiring developers to inspect configuration files and commands themselves.

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.

Any agent

npx skills add brain-bootstrap/claude-code-brain-bootstrap --skill mcp

Clone the repo

git clone --depth 1 https://github.com/brain-bootstrap/claude-code-brain-bootstrap

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	$0.00035	$0.00850
Opus 5.5	$0.00014	$0.00340
Sonnet 5.5	$0.00007	$0.00170
Haiku 4.5	$0.00003	$0.00085

Security

Grade A, and why

mcp 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 1mo 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.

MCP Skill

Manage Model Context Protocol (MCP) servers for this project.

Usage

/mcp                    # List configured servers + invocation format
/mcp status             # Check which tool binaries are installed
/mcp add <server>       # Add a new MCP server
/mcp format             # Show all tool invocation strings

MCP Tool Invocation Format

mcp__SERVER_KEY__TOOL_FUNCTION_NAME

Where SERVER_KEY is the server key in .claude/settings.json under mcpServers.*.

Instructions

If `list` or empty:

Read .claude/settings.json — show currently configured mcpServers entries
Show invocation format for each tool
Suggest additional servers based on tech stack in claude/architecture.md

If `status`:

Check which MCP binaries are installed:

command -v uvx &>/dev/null && echo "uvx: ✅" || echo "uvx: ❌ missing — install via: pip install uv"
command -v npx &>/dev/null && echo "npx: ✅" || echo "npx: ⚠️ missing — install Node.js"
command -v ccc &>/dev/null && echo "cocoindex CLI (ccc): ✅" || echo "cocoindex CLI: ⚠️ optional — install via: pip install cocoindex"
# uvx-based tools (codebase-memory, code-review-graph, serena, cocoindex-code) are available when uvx is installed

If `add <server-name>`:

Prefer CLI: claude mcp add <server-name> -- <command> [args]
- Example: claude mcp add context7 -- npx -y @upstash/context7-mcp
Or manually add to .claude/settings.json under mcpServers.<name>
For HTTP servers requiring OAuth: authenticate after configuration
Update CLAUDE.md — add to Plugin Ecosystem section

If `format`:

Show all available MCP tool invocations from .claude/settings.json.

Pre-Configured MCP Stack

MCP Server Key	Binary	Invocation prefix
`codebase-memory`	`uvx codebase-memory-mcp@latest`	`mcp__codebase-memory__`
`cocoindex-code`	`uvx cocoindex-code-mcp-server@latest`	`mcp__cocoindex-code__`
`code-review-graph`	`uvx code-review-graph@latest`	`mcp__code-review-graph__`

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.

mcp is a skill published in the GitHub repository brain-bootstrap/claude-code-brain-bootstrap (11 stars, last pushed 5mo ago), licensed MIT. It adds 35 tokens to every session and 850 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
