# Sumble ID: 05-sumble Page: https://gtmmcps.com/tools/05-sumble JSON: https://gtmmcps.com/data/tools/05-sumble.json Documentation references: https://gtmmcps.com/docs/05-sumble/ Category: Signals & Intent MCP support: official Testing: RESEARCHED API access: paid Last checked: 2026-09-07 Endpoint check: docs-only; date: 2026-09-04 Builds an account-intelligence knowledge graph by continuously scanning tens of millions of public sources (job boards, company sites, social media, regulatory filings) to map org structure, tech stack, and initiatives like cloud migrations or GenAI projects per company. ## MCP links - https://mcp.sumble.com/ - https://docs.sumble.com/api/mcp - https://sumble.com/mcp - https://github.com/SumbleData/sumble-mcp ## Sources - https://techcrunch.com/2025/10/22/sumble-emerges-from-stealth-with-38-5m-to-bring-ai-powered-context-to-sales-intelligence/ - https://sumble.com/ - https://docs.sumble.com/api/mcp - https://sumble.com/llms.txt - https://sumble.com/mcp - https://mcp.sumble.com/ ## Research notes 2026-08-28 link-rot correction, and the lead paid off. The mcp_url published until today, docs.sumble.com/pages/KLH6XuEHsUssUZW6C1i4, 404d when re-checked on 2026-08-27. It is named here rather than left in the mcp_url field so the published page does not carry a link to a 404. https://sumble.com/llms.txt names the real current surface under a "For AI agents" heading, and both https://sumble.com/mcp and https://docs.sumble.com/api/mcp return 200. The server is alive and first-party, so mcp_status stays official rather than being downgraded. Emerged from stealth October 2025 with a $38.5M raise; knowledge graph covers ~2.6M companies. Self-serve 30-day free trial, no credit card required; specific paid pricing tiers not published. 2026-09-07: https://mcp.sumble.com/ returned 401 {"error": "invalid_token", "error_description": "Authentication required"} to an MCP initialize POST (https://mcp.sumble.com/). 2026-09-12 (P6-04 repo sweep): first-party repository recorded at https://github.com/SumbleData/sumble-mcp - first-party agent skill for the Sumble MCP (README: "Sumble MCP Skill", installed with npx skills add SumbleData/sumble-mcp), NOT the server source. Evidence: the vendor's own docs page https://docs.sumble.com/api/mcp names github.com/SumbleData, which is the domain evidence the 2026-09-09 pass could not find on the org profile. The exact URL that page prints, github.com/SumbleData/sumble, returned 404 on 2026-09-12; the live repository in that same org is sumble-mcp, last pushed 2026-04-14. ## Named capabilities Tool names below are reported by sources.
