**An agent can connect on its own if it already holds `DATAMERGE_TOKEN`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- pass `tools.annotations`: 23 of 23 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_company_enrichment_result (destructiveHint, idempotentHint, openWorldHint); run_contact_search (openWorldHint); get_company (destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 5,322 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 23, about 5,322 tokens to load them all
- tool set hash: df80d1c0afe43290c3286a489b96ff46
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.datamerge/mcp.svg)](https://protogrid.dev/servers/ai.datamerge/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (23)

- `configure_datamerge`: Configure DataMerge API authentication (required before using other tools if DATAMERGE_API_KEY is not set).
- `contact_enrich`: 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.
- `create_list`: POST /v1/lists. Body: name, object_type (company or contact).
- `delete_list`: DELETE /v1/lists/{object_type}/{list_slug}. System lists cannot be deleted.
- `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).
- `get_company_enrichment_result`: GET /v1/company/enrich/{job_id}/status. Poll until status is "completed" or "failed". Response includes record_ids. Status values: queued · processing · completed · failed.
- `get_company_hierarchy`: Get all entities in the same global ultimate hierarchy. GET /v1/company/hierarchy?datamerge_id={id}. Parameters: include_names (bool, charges 1 credit), include_branches (bool), only_subsidiaries (bool), max_level (int), country_code (array), page (int).
- `get_contact`: GET /v1/contact/get?record_id={uuid}. Retrieve a specific contact by record UUID. Never charges credits.
- `get_contact_enrich_status`: GET /v1/contact/enrich/{job_id}/status. Poll until status is "completed" or "failed". Response includes record_ids.
- `get_contact_search_status`: GET /v1/contact/search/{job_id}/status. Poll until status is "completed" or "failed". Response includes record_ids.
- `get_credits_balance`: GET /v1/credits/balance. Returns credits_balance and balances (one_off, recurring, rollover, total).
- `get_list_items`: GET /v1/lists/{object_type}/{list_slug}. object_type: company or contact. list_slug: e.g. target-accounts. Parameters: page, page_size (max 100), sort_by, sort_order (asc/desc).
- `health_check`: Check if the DataMerge API client is configured and can connect. Uses /auth/info.
- `list_lists`: GET /v1/lists. Optional: object_type=company or object_type=contact.
- `remove_list_item`: DELETE /v1/lists/{object_type}/{list_slug}/{item_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.
- `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).
- `start_company_enrichment`: POST /v1/company/enrich. Enrich one or more companies by domain. Returns a job_id (async). Single: domain. Batch: domains, country_code, global_ultimate, list, skip_if_exists.
- `start_company_enrichment_and_wait`: POST /v1/company/enrich then poll GET /v1/company/enrich/{job_id}/status until status is "completed" or "failed" or timeout. Same params as start_company_enrichment plus poll_interval_seconds and timeout_seconds.
