mcp-apollo
An open-source, self-hosted MCP server for Apollo.io — gives your AI agents direct access to Apollo's B2B sales intelligence database.
Deploy it to your own Cloudflare account in under 5 minutes. You own the infrastructure, you control the costs. No shared hosting, no vendor lock-in.
Built and maintained by AgenTeam. MIT licensed.
How it works
Your Cloudflare Workers account
└── mcp-apollo Worker (your deploy, your infra)
└── MCP client sends requests with your Apollo API key
└── Worker proxies to Apollo.io API
└── Returns enriched data to your agentYou deploy the Worker to your own Cloudflare account (free tier handles most use cases)
You pass your own Apollo.io API key on every request — the Worker never stores it
No shared infrastructure — every user runs their own isolated instance

Apollo.io rate limits
Plan | Requests / hour |
Free | 50 |
Basic | 200 |
Professional | 1,000 |
Organization | Custom |
The server returns rate limit metadata with every response (rate_limits.remaining, rate_limits.resetAt). On 429 errors it returns an informative message — it never silently fails.
Cloudflare Workers free tier
Metric | Free limit |
Requests | 100,000 / day |
CPU time | 10ms / request |
100k requests/day is enough for most individual or small-team deployments. If you exceed it, upgrade to the Workers Paid plan ($5/month for 10M requests).
Local development
npm install
npm run dev
# Server runs at http://localhost:8787Run tests
npm test # unit + RALPH-loop tests
APOLLO_API_KEY=your_key npx vitest run test/e2e # E2E against live Apollo APICI/CD on your fork
The repo includes GitHub Actions workflows:
ci.yml— runs typecheck, build check, and tests on every pushdeploy.yml— deploys to Cloudflare Workers on merge tomaine2e.yml— nightly E2E tests against the live Apollo API
To enable auto-deploy, add these secrets in your fork under GitHub → Settings → Secrets → Actions:
Secret | Where to get it |
| Cloudflare Dashboard → My Profile → API Tokens → Create Token (use "Edit Cloudflare Workers" template) |
| Cloudflare Dashboard → Workers & Pages → right sidebar |
To enable nightly E2E tests, also add APOLLO_API_KEY as a secret and set the repo variable APOLLO_E2E_ENABLED to true.
Security
Your Apollo API key is passed as a
Bearertoken in theAuthorizationheader on each requestThe Worker never stores, logs, or persists your API key
Each request is stateless — the key is used only for that request's Apollo API call
You control the entire deployment — no data touches third-party infrastructure

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.
Your agent needs a pipeline, not a list — the companies worth calling, the people who decide inside them, a way to reach those people, and the market evidence that the account is worth the call. **What you can ask for** • "Find Series-B fintech companies in Germany and the heads of marketing there, with emails." • "Enrich these 200 domains with headcount, funding and tech stack." • "Which of these accounts is hiring for roles that imply they need us?" • "How much traffic does this prospect get, and where does it come from?" • "Create the account and contact records and move this opportunity to the next stage." **How to use it** Point any MCP client at https://mcp.aisa.one/sales/mcp and sign in with OAuth — there is no key to create or paste. 79 tools: Apollo people and company search, enrichment, accounts, contacts, opportunities and stages, job postings, sequences and call activity; Similarweb traffic, audience, referrals, ad spend and competitors; plus creator discovery. **Why this rather than the source** Prospecting, enrichment, market sizing and the CRM writes behind one login instead of three. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Build the list here, then ask the same agent what those companies rank for or what is being said about them — 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/apollo/mcp or https://mcp.aisa.one/similarweb/mcp for one of them alone; https://mcp.aisa.one/gtm/mcp adds the social side.
