# Add optional MCPcat analytics scaffolding (`--with-mcpcat`) to generated MCP servers
|
||||
|
||||
> **TL;DR**: This PR adds an **opt-in** flag to scaffold privacy-safe analytics wiring for MCPcat in projects generated by `openapi-mcp-generator`.
|
||||
|
||||
## Summary
|
||||
This PR introduces a `--with-mcpcat` CLI flag that scaffolds:
|
||||
- A tiny analytics shim to emit initialize/tool-call events.
|
||||
- A default **local redaction** helper to scrub sensitive data before export.
|
||||
- Minimal config via environment variables.
|
||||
No behavior changes unless the flag and env vars are set.
|
||||
|
||||
## Motivation
|
||||
- Make freshly generated MCP servers **observable in minutes**.
|
||||
- Encourage **privacy-by-default** analytics patterns.
|
||||
- Reduce copy/paste wiring; standardize event shape (operationId, path, duration, status).
|
||||
|
||||
## Changes
|
||||
### CLI
|
||||
- `generate` accepts `--with-mcpcat` (default: off).
|
||||
|
||||
### Template files (added conditionally)
|
||||
- `src/analytics/mcpcat.ts` – lazy import + safe no-op if SDK absent.
|
||||
- `src/analytics/redact.ts` – OpenAPI-aware heuristics (e.g., `*token*`, `password`, `apiKey`, `authorization`, `email`).
|
||||
- `src/analytics/config.ts` – reads env:
|
||||
- `MCPCAT_ENABLED=true|false` (default `false`)
|
||||
- `MCPCAT_PROJECT_ID=<id>`
|
||||
- `MCPCAT_ENDPOINT=<optional override>`
|
||||
- `MCPCAT_SAMPLE_RATE=1.0` (0–1)
|
||||
|
||||
### Server wiring
|
||||
- Hooks server `.initialize` and each tool invocation to record:
|
||||
- `operationId`, HTTP `method`, `path`
|
||||
- redacted `args`
|
||||
- `outcome` (`ok`/`error`) + truncated error message
|
||||
- `duration_ms`
|
||||
|
||||
### Docs
|
||||
- Adds a “Enable analytics (MCPcat)” section to generated README with privacy notes and quickstart.
|
||||
|
||||
## Implementation Notes
|
||||
- **Compile-time optional**: no imports unless flag is used.
|
||||
- **Runtime safe**: try/catch around SDK import → graceful no-op if not installed.
|
||||
- **Transport-agnostic**: compatible with stdio, SSE/web, and StreamableHTTP templates.
|
||||
- **Edge-friendly**: avoids Node-only APIs in scaffolding to support edge runtimes (e.g., Workers).

## 🔎 Filtering Endpoints with OpenAPI Extensions
|
||||
|
||||
You can control which operations are exposed as MCP tools using a vendor extension flag `x-mcp`. This extension is supported at the root, path, and operation levels. By default, endpoints are included unless explicitly excluded.
|
||||
|
||||
- Extension: `x-mcp: true | false`
|
||||
- Default: `true` (include by default)
|
||||
- Precedence: operation > path > root (first non-undefined wins)
|
||||
- CLI option: `--default-include false` to change default to exclude by default
|
||||
|
||||
Examples:
|
||||
|
||||
```yaml
|
||||
# Optional root-level default
|
||||
x-mcp: true
|
||||
|
||||
paths:
|
||||
/pets:
|
||||
x-mcp: false # exclude all ops under /pets
|
||||
get:
|
||||
x-mcp: true # include this operation anyway
|
||||
|
||||
/users/{id}:
|
||||
get:
|
||||
# no x-mcp -> included by default
|
||||
```
|
||||
|
||||
This uses standard OpenAPI extensions (x-… fields). See the [OpenAPI Extensions guide](https://swagger.io/docs/specification/v3_0/openapi-extensions/) for details.
|
||||
|
||||
Note: `x-mcp` must be a boolean or the strings `"true"`/`"false"` (case-insensitive). Other values are ignored in favor of higher-precedence or default behavior.

## Token Caching
|
||||
|
||||
The MCP server automatically caches OAuth tokens obtained via client credentials flow. Tokens are cached for their lifetime (as specified by the `expires_in` parameter in the token response) minus 60 seconds as a safety margin.
|
||||
|
||||
When making API requests, the server will:
|
||||
|
||||
1. Check for a cached token that's still valid
|
||||
2. Use the cached token if available
|
||||
3. Request a new token if no valid cached token exists

- `OAUTH_CLIENT_SECRET_PETSTORE_AUTH`: Your OAuth client secret

## Token Caching
|
||||
|
||||
The MCP server automatically caches OAuth tokens obtained via client credentials flow. Tokens are cached for their lifetime (as specified by the `expires_in` parameter in the token response) minus 60 seconds as a safety margin.
|
||||
|
||||
When making API requests, the server will:
|
||||
|
||||
1. Check for a cached token that's still valid
|
||||
2. Use the cached token if available
|
||||
3. Request a new token if no valid cached token exists
