Fulcru MCP - AI Search Visibility with Execution Arm¶

Priority: HIGH | Category: Marketing / SEO
Transport: Remote Streamable HTTP | Auth: Bearer token
Repository: gsmmediaro/fulcru-agent (AGPL-3.0)
Website: https://fulcru.app
Discovered: July 27, 2026 (chatmcp/mcpso #3318)

What It Does for Operators¶

Fulcru finds the questions where ChatGPT, Gemini, and Perplexity name your competitor instead of you - then writes the page that closes that gap and measures whether it worked. Most AI-visibility tools stop at a score. Fulcru carries the loop all the way through to measured outcomes.

This is the first MCP server that closes the AI-SEO loop end-to-end. For business operators who depend on AI-driven search traffic, knowing what AI assistants say about your brand vs competitors is existential.

Operator Use Cases¶

Competitive AI share-of-voice: "What questions do ChatGPT/Gemini answer with a competitor's brand instead of ours?" - run fulcru_gaps, identify top 5 competitor mentions, prioritize by search volume
Content ROI measurement: Publish a page targeting a specific AI query, then measure fulcru_delta after 2 weeks to see if AI assistants now cite your brand instead
Product launch monitoring: When launching a new feature, use fulcru_visibility to track whether AI assistants surface it when users ask about the category
M&A due diligence: Check a target company's AI visibility before acquisition - are they winning the AI search war in their category?
Agency reporting: For operators running client engagements, Fulcru provides hard numbers on AI visibility improvement

Integration with CorpusIQ¶

Complementary. CorpusIQ provides cross-source business data (financials, operations, marketing analytics). Fulcru adds the AI-search layer that's increasingly critical for operator decision-making. Operators could use CorpusIQ to identify revenue-impacted segments, then use Fulcru to close the AI-visibility gaps in those segments.
