A skill your agent uses when the user says 'what MCP servers', 'find an MCP for', 'hosted MCP', 'list MCP servers', 'MCP catalog', 'available MCP tools', or needs to discover zero-setup hosted MCP…

  • Works in 3 steps: Identify the need → Add to config → Test the connection
  • The user says what MCP servers
  • SKILL.md covers Activation, Context Guard, How Hosted MCP Works and Catalog: Official Platform MCP…, plus 5 more sections
  • Reaches mcp.vercel.com and mcp.supabase.com

What it does

Memstack Automation Hosted MCP Catalog is an agent skill from cwinvestments/memstack. Use when the user says 'what MCP servers', 'find an MCP for', 'hosted MCP', 'list MCP servers', 'MCP catalog', 'available MCP tools', or needs to discover zero-setup hosted MCP servers they can use immediately. Do NOT use for building MCP servers or configuring local MCP.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol and Vercel. The repository describes itself as: Structured skill framework for Claude Code. 130 skills, persistent memory, TokenStack compression, localhost dashboard with 3-agent runner, real-time streaming, MCP tools. The licence is MIT.

When your agent uses it

  • The user says what MCP servers
  • Find an MCP for
  • List MCP servers
  • Available MCP tools

Example prompts

  • “what MCP servers”
  • “find an MCP for”
  • “hosted MCP”
  • “/memstack-automation-hosted-mcp-catalog”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Identify the need
  2. Add to config
  3. Test the connection

What it can do on your machine

Read from SKILL.md and the folder at commit 00370ce. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • mcp.vercel.com
    • mcp.supabase.com
    • mcp.sentry.dev
    • mcp.stripe.com
    • mcp.linear.app
    • mcp.slack.com
    • api.greptile.com

    Also links to:

    • github.com
    • smithery.ai
    • mcp.so
    • glama.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Memstack Automation Hosted MCP Catalog loads about 1.2k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 459 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

TriggerStatus
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 serverNOT this skill: use mcp-builder
User wants to configure local MCPNOT 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:

json
{
  "mcpServers": {
    "server-name": {
      "type": "url",
      "url": "https://example.com/mcp"
    }
  }
}

In Claude Desktop: add to claude_desktop_config.json:

json
{
  "mcpServers": {
    "server-name": {
      "url": "https://example.com/mcp"
    }
  }
}

Catalog: Official Platform MCP Servers

These are maintained by major platforms and generally stable:

ServerURLToolsUse Case
Vercelhttps://mcp.vercel.comDeploy, logs, env vars, projectsVercel deployment management
Supabasehttps://mcp.supabase.com/mcpDB queries, migrations, RLSDatabase management
Sentryhttps://mcp.sentry.dev/mcpIssues, errors, performanceError tracking
Stripehttps://mcp.stripe.comPayments, customers, invoicesPayment processing
Linearhttps://mcp.linear.app/mcpIssues, projects, cyclesProject management
Slackhttps://mcp.slack.com/mcpMessages, channels, searchTeam communication
Greptilehttps://api.greptile.com/mcpCodebase search, understandingCode intelligence

Note: Most official servers require OAuth authentication on first use. Claude Code handles this automatically, you'll get a browser prompt to authorize.

How to Choose

When the user needs an MCP server, help them find the right one:

Show full SKILL.md (184 more words)Show less
Step 1: Identify the need
User wants to...Recommended MCP
Query a databaseSupabase
Track errors/bugsSentry
Deploy codeVercel
Process paymentsStripe
Manage issues/ticketsLinear
Send team messagesSlack
Search codebasesGreptile
Step 2: Add to config

Generate the .mcp.json entry for the chosen server:

json
{
  "mcpServers": {
    "<server-name>": {
      "type": "url",
      "url": "<server-url>"
    }
  }
}
Step 3: Test the connection

After adding, restart Claude Code and verify:

  1. The server appears in the MCP tools list
  2. Authentication completes (if required)
  3. A simple tool call succeeds

Discovery Resources

When the catalog above doesn't cover the user's need:

ResourceURLDescription
Anthropic MCP Registryhttps://github.com/modelcontextprotocol/serversOfficial MCP server list
Smitheryhttps://smithery.aiMCP server marketplace
MCP.sohttps://mcp.soCommunity MCP directory
Glamahttps://glama.ai/mcp/serversCurated MCP catalog

Output Template

MCP Server: [name]
URL: [endpoint]
Auth: [OAuth / API key / None]
Tools available: [list of key tools]
Config to add to .mcp.json:

{
  "mcpServers": {
    "[name]": {
      "type": "url",
      "url": "[endpoint]"
    }
  }
}

Restart Claude Code after adding.

Disambiguation

  • "what MCP servers" / "find an MCP for" / "hosted MCP" = Hosted MCP Catalog
  • "build an MCP server" / "create MCP tools" = mcp-builder (not this skill)
  • "MCP not connecting" / "MCP error" = Debug directly (not this skill)
  • "what tools do I have" = Check current MCP config (not this skill)
