If you're after an mcp-gsc alternative, you've probably hit its one hard limit. mcp-gsc is the most popular open-source Search Console MCP server on GitHub, MIT licensed with 20 tools and good docs. It runs on your machine and reads the live Search Console API, so it can't see further back than the API does. That's 16 months.
Month17 speaks the same protocol, runs hosted and reads from an archive that keeps every month.

mcp-gsc and Month17 side by side
| mcp-gsc | Month17 | |
|---|---|---|
| History it can query | 16 months, the live API window | Everything since you connected, plus a 16-month backfill |
| Where it runs | On your machine, via uvx or Python 3.11+ | Hosted, one URL in your MCP config |
| Google auth | Your own OAuth client or a service account | Sign in with Google once |
| URL inspection and sitemaps | Yes | No |
| Analyses that need old data | No | year_over_year, seasonal_patterns, content_decay, core_update_impact |
| Price | Free, open source | Free in early access, then $10 per site per month |
Keep mcp-gsc for recent data, URL inspection and sitemaps
If your questions stay inside the last few months, mcp-gsc answers them for free. It also inspects URLs and manages sitemaps, which Month17 doesn't do at all. Developers who like running their own tools and owning the OAuth setup won't miss anything.
Switch to Month17 for questions older than 16 months
Did this page recover from an update two years ago? Is the spring dip seasonal? How did this year compare with last year? A live-API server can't answer any of them, because the data it would need is deleted.
There's also less to run. Month17 needs no Google Cloud project and no local process, just one config block, covered in the Claude setup guide. The MCP server page lists all 22 tools.
Running both costs nothing during early access
You can keep mcp-gsc for URL inspection and add Month17 for history, since an MCP client can load both servers at once. Connect the archive first, though. It can only keep what Google still holds on the day you connect, and that window loses a day every day.
