About OpenSDR
OpenSDR is an MCP server published by the GitHub account arif-js. Open-source AI SDR: B2B prospecting, email enrichment, buying signals and safe outreach staging.
It runs on your own machine: your AI client starts it from the npm package opensdr-mcp at version 1.0.1.
It asks for 6 secrets: APOLLO_API_KEY, HUNTER_API_KEY, EXA_API_KEY, TAVILY_API_KEY, INSTANTLY_API_KEY and HUBSPOT_ACCESS_TOKEN. Give it a key with the least access that still works.
Version 1.0.1 was published on 15 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 1 warn, 0 fail, 1 info. How we check.
