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 5.1 | $0.00074 | $0.01190 |
| Opus 5 | $0.00037 | $0.00595 |
| Sonnet 5 | $0.00015 | $0.00238 |
| Haiku 4.5 | $0.00007 | $0.00119 |
Grade A, and why
memstack-automation-hosted-mcp-catalog 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hosted MCP Catalog: Finding hosted MCP servers...
Reference guide for zero-setup hosted MCP servers that require no API keys, no local install, just point any MCP client at the URL.
Activation
| Trigger | Status |
|---|---|
| User says "what MCP servers" or "find an MCP for" | ACTIVE |
| User says "hosted MCP" or "MCP catalog" | ACTIVE |
| User says "available MCP tools" or "list MCP servers" | ACTIVE |
| User wants to BUILD an MCP server | NOT this skill: use mcp-builder |
| User wants to configure local MCP | NOT this skill: check .mcp.json docs |
Context Guard
- Do NOT use for building MCP servers (that's mcp-builder Pro skill)
- Do NOT use for local MCP server configuration
- Do NOT use for debugging MCP connection issues
- This skill ONLY helps discover and connect to hosted MCP endpoints
How Hosted MCP Works
Hosted MCP servers run remotely: no local install needed. Add the URL to your MCP client config and the tools are available immediately.
In Claude Code: add to .mcp.json:
{
"mcpServers": {
"server-name": {
"type": "url",
"url": "https://example.com/mcp"
}
}
}
In Claude Desktop: add to claude_desktop_config.json:
{
"mcpServers": {
"server-name": {
"url": "https://example.com/mcp"
}
}
}
Catalog: Official Platform MCP Servers

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.
