Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

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`destructive	DELETE /v1/lists/{object_type}/{list_slug}. System lists cannot be deleted.
`get_company`read-only	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`read-only	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`read-only	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`read-only	GET /v1/contact/get?record_id={uuid}. Retrieve a specific contact by record UUID. Never charges credits.
`get_contact_enrich_status`read-only	GET /v1/contact/enrich/{job_id}/status. Poll until status is "completed" or "failed". Response includes record_ids.
`get_contact_search_status`read-only	GET /v1/contact/search/{job_id}/status. Poll until status is "completed" or "failed". Response includes record_ids.
`get_credits_balance`read-only	GET /v1/credits/balance. Returns credits_balance and balances (one_off, recurring, rollover, total).
`get_list_items`read-only	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`read-only	Check if the DataMerge API client is configured and can connect. Uses /auth/info.
`list_lists`read-only	GET /v1/lists. Optional: object_type=company or object_type=contact.
`remove_list_item`destructive	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.

Schemas: list_tools.
