Source credits view-through ad exposures alongside click-through, records UTMs and referrer data on every visit, pulls organic queries from Google Search Console with a confidence score, and applies weights across six attribution models (first touch, last touch, linear, position based, and linear and exponential time decay). Query tools are read-only and scoped to approved websites, run_sql accepts SELECT queries only, only org admins can save a funnel, and every answer returns the SQL behind it; Source says it has completed a SOC 2 Type II examination and holds ISO 27001 certification.", "body_md": "Source turns your website and CRM data into attribution your agents can query over MCP.\n\nYour agent adds the Source snippet to your site and checks that sessions arrive.\n\nMove spend to the channels whose visits turn into pipeline.\n\nChoose AEO and SEO topics from the pages that show up in deal journeys.\n\nPost attribution by channel to your team on a schedule.\n\nAdd https://api.source.app/mcp as a custom connector, then sign in to Source.\n\nSource is listed in the OpenAI marketplace, so you can add it to ChatGPT from there.\n\nOpen Settings, then API keys, in Source and copy the Cursor config from Connect an AI client.\n\nRun claude mcp add with your API key. The full command is under Connect an AI client.\n\nOne path per buyer, from the first ad view to the closed deal.\n\nSource credits the ad a buyer saw but never clicked when that buyer later books a meeting or closes a deal. View-through sits next to click-through on the same path, so you can compare the two.\n\nSource records the UTMs and referrer on every visit, so tagged links in your outbound sequences land on the same path as ads and content. Add calls and meetings as offline touches, then ask which sequences sourced pipeline.\n\nSource pulls organic queries from Google Search Console and estimates which query brought in each contact, with a confidence score. See which searches turn into meetings and deals.\n\nEvery touch carries a weight for six models: first touch, last touch, linear, position based, and linear and exponential time decay. Switch models to see how credit moves between channels.\n\nYour agent finds the tables, runs the query and shows its work. Every answer includes the SQL behind it, so you can check how each number was calculated.\n\nAsk which campaigns sourced pipeline last quarter. Returns the answer, the SQL behind it, the result table and follow-up questions.\n\nRun a read-only BigQuery SELECT against your attribution data.\n\nList tables and columns, with guidance on which answers what.\n\nList the websites a credential can query.\n\nSet the funnel stages Source uses for your website.\n\nGet install steps for the Source pixel on your site.\n\nGet steps for mapping your CRM stages to the funnel.\n\nReport an answer that was wrong or misleading.\n\nQuery tools are read-only and scoped to the websites you approve. run_sql accepts SELECT queries only, and only org admins can save a funnel.\n\nSign up, then add the Source pixel to your site.\n\nBring meetings, deals and revenue onto the same path as visits.\n\nPaste the MCP config into your client and sign in.\n\n```\n{\n  \"mcpServers\": {\n    \"source\": {\n      \"url\": \"https://api.source.app/mcp\"\n    }\n  }\n}\n```\n\nSource has completed a SOC 2 Type II examination and is ISO 27001 certified.

Revoke a connection any time in Settings, then API keys, then Connected apps.\n\nQuery tools are read-only and limited to the websites you approve.
