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.

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 | $0.00065 | $0.01748 |
| Opus 5 | $0.00032 | $0.00874 |
| Sonnet 5 | $0.00013 | $0.00350 |
| Haiku 4.5 | $0.00006 | $0.00175 |
Grade A, and why
skillmcp 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 3d 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.

SkillMCP MCP Server Integration
A guide and operational workflow for discovering, searching, inspecting, and retrieving AI agent skills via the SkillMCP (Skill Management System) Model Context Protocol (MCP) server.
SkillMCP delivers a centralized, horizontally scalable skill repository designed for autonomous agent fleets. It uses Stateless Streamable HTTP by default, allowing request/response decoupling across multiple backend replicas without requiring sticky sessions.
🚀 Quick Start
1. Transport & Connection Matrix
| Transport Mode | Endpoint URL | HTTP Method | Header Requirements | Statefulness |
|---|---|---|---|---|
| Streamable HTTP | http://<host>:8080/mcp |
POST |
Accept: application/json, text/event-streamContent-Type: application/json |
Stateless (horizontally scalable, HPA ready) |
| Health Check | http://<host>:8080/healthz |
GET |
None | Stateless |
2. Antigravity MCP Client Configuration (mcp_config.json)
To register a remote SkillMCP instance in Antigravity or standard MCP client configurations:
{
"mcpServers": {
"skillmcp": {
"type": "http",
"url": "http://localhost:8080/mcp"
}
}
}
🛠️ Workflows
Workflow 1: Connecting & Validating Server Health
- Verify Backend Health & Readiness:
Send a
GETrequest tohttp://<host>:8080/healthz.- Expected Status:
200 OK - Expected Body:
{"status": "healthy", "service": "skillmcp", "version": "<version>"}
- Expected Status:
- Perform Stateless JSON-RPC Handshake:
Send an
initializeJSON-RPC request to/mcpwith headerAccept: application/json, text/event-stream:{ "jsonrpc": "2.0", "id": 1, "method": "initialize", "params": { "protocolVersion": "2024-11-05", "capabilities": {}, "clientInfo": { "name": "agent-client", "version": "1.0.0" } } } - Verify Server Capabilities:
Ensure the response confirms protocol version
2024-11-05and advertisestools,prompts, andresources.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 3d ago First seen · 189 lines · 65 tokens per session scan A 781c85409d3b
skillmcp is a skill published in the GitHub repository clivechung/skillmcp (0 stars, last pushed 3d ago), licensed MIT. It adds 65 tokens to every session and 1,748 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
