Nothing serious here today

Today is the operative word: we check DataMerge MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

POST /v1/contact/enrich. Enrich specific contacts by LinkedIn URL or name+domain. Returns a job_id (async, 202).

contact_search

POST /v1/contact/search. Search for contacts at specified companies. Returns a job_id (async, 202). enrich_fields required (at least one of contact.emails or contact.phones). Use company_list (slug) instead of domains to search a saved list.

contact_search_unenriched

POST /v1/contact/search/unenriched. Find contacts without running email/phone enrichment. Returns a job_id; contacts are created in `unconfirmed` status with stable ids. BETA: requires the `contact_search_unenriched` flag on the account.

GET /v1/contact/search/{job_id}/status. Poll until status is "completed" or "failed". Response includes record_ids.

run_contact_enrich

Agent-friendly contact enrichment. On the first call provide contacts and enrich_fields; the server starts the job and polls internally for up to ~25s. If still running, returns {status:"pending", continuation_token, attempt, elapsed_seconds} — you MUST immediately call run_contact_enrich again with only continuation_token set. Do not ask the user. Typical jobs finish within 5 attempts. On completion the response contains record_ids and full contact records.

run_contact_search

Agent-friendly contact search. On the first call provide domains and enrich_fields; the server starts the job and polls internally for up to ~25s. If still running, returns {status:"pending", continuation_token, attempt, elapsed_seconds} — you MUST immediately call run_contact_search again with only continuation_token set. Do not ask the user. On completion the response contains record_ids, full contact records, and credits_consumed.

run_contact_search_unenriched

POST /v1/contact/search/unenriched/sync. Synchronous unenriched contact search — returns contacts inline (no polling). Requires the `contact_search_unenriched` beta flag. Limits: 10 domains and max_results_per_company ≤ 10. Response includes credits_consumed computed as 0.5 × len(contacts).

company

get_company

Get a single company record. GET /v1/company/get?datamerge_id={id} or ?record_id={uuid}. Provide either datamerge_id (charges 1 credit) or record_id (free). Not both. Optional: add_to_list — list slug to add the company to (only with datamerge_id).

run_company_enrichment

Agent-friendly company enrichment. On the first call provide enrichment params (domain, domains, company_name, country_code, etc.); the server starts the job and polls internally for up to ~25s. If the job is still running, the response will be {status:"pending", continuation_token, attempt, elapsed_seconds}. When you see status "pending" you MUST immediately call run_company_enrichment again with only continuation_token set — do not ask the user, do not call any other tool first. Typical jobs finish within 5 attempts (~125s). On completion the response contains record_ids and full company records.

DataMerge MCP — questions

Answers built from our own checks of this server.

What can DataMerge MCP do?

It exposes 23 tools, read directly from the server on our last check. Among them: configure_datamerge, contact_enrich, contact_search, contact_search_unenriched, create_list, delete_list and 17 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is DataMerge MCP mostly used for?

Its tools cluster around contact, company and start. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is DataMerge MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 321 ms. The bar chart above shows every period we have measured.

How do I connect DataMerge MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does DataMerge MCP need an API key?

No. DataMerge MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 23 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is DataMerge MCP?

It answers our handshake in 321 ms on average, which is faster than 48% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
