Google Search Console MCP server for Claude — connect by URL at https://gsc.k-o.pro/mcp and sign in with Google, or run it locally. 33 SEO analysis tools across every property in your account: quick wins, traffic-drop diagnosis, content decay, cannibalisation, CTR opportunities, multi-site dashboards and a full image-search suite. Per-user MCP OAuth (PKCE, DCR) so a team shares one deployment and each person sees only their own properties.
33 tools with consistent naming (verb_noun pattern) and descriptions. All tools have input schemas with typed parameters and descriptions. However, output schemas are not documented, LLMs cannot predict response structure. Many parameter descriptions lack constraints (ranges, enums, formats). Error handling guidance is absent. Tool descriptions average ~120 chars (below 194-char baseline), missing WHEN/WHY context. No tool annotations (readOnlyHint/destructiveHint). Composition is sound: tools chain via site_url parameter; batch variants exist (submit_batch). Security: no secrets in params (OAuth handled server-side). Naming is clear and action-oriented (quick_wins, traffic_drops, inspect_url), but some tools are vague (advanced_search_analytics, content_recommendations lack specificity on what they return).
Run advanced queries against Search Analytics with full filtering and grouping options.
Find keywords where multiple pages from your site compete against each other. Shows which page ranks higher, the position gap, and combined impressions being split.
Check for active alerts and issues in Search Console.
Compare web search performance against image search performance.
Find pages that are slowly dying with consistent traffic decline over three consecutive 30-day periods. One bad month is noise; three consecutive bad months is a problem.
Find topics you should create content for. Returns queries where you get impressions but rank beyond position 20, meaning there is search demand but no real content targeting it.
Output schemas not documented. LLMs cannot predict response structure, forcing them to guess what fields are returned and how to chain tools. Baseline: 100% of A+ tools document return types.

Parameter descriptions lack constraints. 'days' accepts any number; should specify range (1 - 365). 'min_impressions' unbounded; should specify realistic range. Baseline: 100% of A+ tools include format, range, and allowed values in param descriptions.
No tool annotations (readOnlyHint, destructiveHint, idempotentHint). Agents cannot distinguish safe reads from destructive writes. disconnect_account and submit_* tools should be marked destructive; all read tools should be marked readOnly.
Tool descriptions lack WHEN/WHY context. 'advanced_search_analytics' and 'content_recommendations' are vague about what they return and when to use them vs similar tools. Baseline: descriptions should answer WHAT, WHEN, and WHAT IT RETURNS.
No error handling guidance. Tools do not document what errors can occur, whether they are retryable, or what the LLM should do next. E.g., 'inspect_url' may fail if URL is invalid or not in Search Console, no guidance provided.
