## Record Details

**Name:**

**Description:**

**Record version:**

**Record type:** MCP

---

## MCP Server Definition

Copy-paste the JSON below into the "Your MCP server definition" editor:

```json
{
  "name": "<namespace/slug, must match ^[a-zA-Z0-9.-]+/[a-zA-Z0-9._-]+$>",
  "description": "<max 100 chars, concise description>",
  "version": "<version>",
  "remotes": [
    {
      "type": "<transport type, e.g. streamable-http>",
      "url": "<MCP_URL>"
    }
  ]
}

{
  "tools": [
    <for each tool, include the full tool object with name, description, and inputSchema>
  ]
}

#### Rules for populating the template

- **Record name**: Convert the server name to a valid AgentCore record ID. Use lowercase, replace spaces and hyphens with underscores, prefix with `record_`. Only use letters, digits, underscores. Example: `record_novacolor_finishes`.
- **Description**: Write a concise 1-2 sentence description based on the server name and tool names/descriptions.
- **Transport**: Determine from how the server responded:
  - If the initialize response included `mcp-session-id` header and responded to POST with JSON, use `streamable-http`.
  - If the server used SSE (event-stream responses for initialize), use `sse`.
  - Default to `streamable-http` for remote HTTP servers.
- **MCP server definition JSON**: Must include `name`, `description`, `version`, and `remotes` fields. The `remotes` array contains the transport type and URL so that the AgentCore sync can extract `proxy_pass_url` correctly via `remotes[0].url`.
  - **name** MUST match the pattern `^[a-zA-Z0-9.-]+/[a-zA-Z0-9._-]+$` (namespace/name format). Derive the namespace from the server's domain (e.g., `com.agenthost` for `agenthost.club`, `io.github.user` for GitHub). Example: `com.agenthost/novacolor-italian-finishes`.
  - **description** MUST be 100 characters or fewer. Keep it concise.
  - **remotes** MUST be an array with at least one object containing `type` (transport type) and `url` (the MCP endpoint URL). Do NOT use top-level `url` and `transport` fields -- use the `remotes` array format instead.
- **Tool definition JSON**: Include the complete tool objects exactly as returned by the server, wrapped in a `{"tools": [...]}` envelope.
- **Tool inputSchema**: Include the full inputSchema for each tool exactly as returned by the server. Do NOT simplify or omit properties.

### 4. Cleanup

Remove temporary files:

```bash
rm -f /tmp/_agentcore_mcp_headers.txt /tmp/_agentcore_mcp_init.json /tmp/_agentcore_mcp_tools.json

User: /agentcore-register https://novacoloritalianfinishes.agenthost.club/mcp

Output:
Generated `.scratchpad/agentcore-register-novacolor.md`

Summary:
- Server: some-agent (v0.1)
- Transport: streamable-http
- Tools: 3 (search_site_products, search, fetch)

Open the file and copy-paste each section into the AgentCore "Create record" form.
