Your agent needs B2B contacts and the pipeline objects around them — find the company, find the person, get the email, then write it back where your team works. **What you can ask for** • "Find heads of engineering at Series-B SaaS companies in the Nordics, with emails." • "Enrich these companies with headcount, industry and funding." • "What roles is this company hiring for right now?" • "Create an account and a contact, then log this opportunity." • "Search our sequences for messages sent to this domain." **How to use it** Point any MCP client at https://mcp.aisa.one/apollo/mcp and sign in with OAuth — there is no key to create or paste. 54 tools: people and organisation search and enrichment, job postings, accounts, contacts, opportunities and their stages, custom fields, labels, notes, users, email accounts, sequence messages and phone-call search — reads and writes. **Why this rather than the source** The full object model, not just a search endpoint, so an agent can finish the job rather than hand you a CSV. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the person here, then ask the same agent what their company's traffic looks like or what they rank for — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/sales/mcp adds Similarweb and creator discovery around it.
