What is count-mcp-tools?

A skill that counts MCP tools in an SDK project and compares the results with a .discover.json manifest. MCP tools are callable functions that connect an agent to outside services or project features.

It is for checking tool totals, collection coverage, project progress, and remaining testing gaps.

It shows how many tools exist, where they are grouped, and which collections lack implementation, integration tests, or evaluation tests.

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	$0.00037	$0.00909
Opus 5.5	$0.00015	$0.00364
Sonnet 5.5	$0.00007	$0.00182
Haiku 4.5	$0.00004	$0.00091

Security

Grade A, and why

count-mcp-tools 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/count-tools.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Count MCP Tools

This skill counts all MCP tools in the project and provides a detailed breakdown by collection. When a .discover.json manifest exists, it also performs gap analysis showing which collections have tools, integration tests, and eval tests.

When to Use

Use this skill when:

User asks "how many tools do we have?"
User wants statistics about tool collections
User needs to know tool distribution across collections
User asks about project progress or coverage
User wants to evaluate skill/agent completion status
User asks which collections still need tests or evals

Instructions

Run the counting script from the consumer project root:

npx tsx ${CLAUDE_PLUGIN_ROOT}/skills/count-mcp-tools/scripts/count-tools.ts

To also show all tool names in the console output:

SHOW_TOOLS=true npx tsx ${CLAUDE_PLUGIN_ROOT}/skills/count-mcp-tools/scripts/count-tools.ts

To save results to a markdown file:

OUTPUT_FILE=docs/analysis/api-endpoints-analysis.md npx tsx ${CLAUDE_PLUGIN_ROOT}/skills/count-mcp-tools/scripts/count-tools.ts

Present results showing:
- Total tool count
- Breakdown by collection (sorted alphabetically)
- List of individual tool names per collection (when SHOW_TOOLS=true or in markdown output)
- Gap analysis table (when .discover.json exists)
- If OUTPUT_FILE is set, saves to markdown file with full tool listing

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.
