On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 202 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 2 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• upload_attachment

  Upload base64 file bytes as reusable source material; returns id and requires_capability. Pass the ID in attachment_ids to sample/schema generation, enrichment or benchmarks. Supported format handling depends on server MIME policy…

• delete_attachment

  Permanently delete an attachment in your organization, including its stored file. No LLM call. Existing records remain, but future calls or schema regeneration cannot reuse the deleted source. Delete only when that source is no longer…

• start_batch_enrichment

  Start billed asynchronous enrichment of an entity list against exactly one of schema_id or target_schema. Returns job_id and total. No fixed entity-count cap; live prompt quotas and credits can stop remaining work. Each entity follows the…

• list_benchmark_scenarios

  List compact benchmark scenario summaries and total. Scenarios test enrichment, sample generation or schema generation. No LLM call. Read one with get_benchmark_scenario or create one with create_benchmark_scenario. Lifecycle and…

• get_benchmark_scenario

  Read one benchmark scenario with per-model quality, cost and speed results. include_reference=true adds the reference, the fixed entity_data and the schema-generation entity_samples. Config changes can make existing results stale. No LLM…

• get_benchmark_scenario_results

  Filter, rank and limit a scenario's per-model benchmark results. No LLM call. overall blends quality, speed and cost using organization task weights and is null if a component is missing. Status tags are independent: success does not…

• create_benchmark_scenario

  Create a reusable benchmark with a mandatory scoring judge. scenario_type='enrichment' needs schema_id and entity_data (the entity to enrich, as enrich_entity takes it — refused when it carries no value; never put it in description)…

• update_benchmark_scenario

  Edit a benchmark's test definition or scoring configuration. Requires owner and a plan with benchmarks; no model run. Only supplied fields change, but sample_params and schema_gen_params replace their parameter objects wholesale. The…

• set_benchmark_reference

  Save the gold reference for an enrichment or schema-generation benchmark. Only set reference_verified=true after checking its values against trusted evidence or obtaining human sign-off; a generated answer alone is not verification…

• revert_benchmark_reference_updates

  Undo automatic edits a scoring pass made to a scenario's reference. Every scoring pass folds what the scored models showed the reference should be (a candidate the judge found better, a rule the samples prove, a value the reference…

• delete_benchmark_scenario

  Delete a benchmark scenario and its stored results. Requires owner and a plan with benchmarks. No LLM call; inspect the scenario before deleting it.

• run_benchmark

  Start billed asynchronous execution and scoring of a benchmark. Requires owner, a benchmark-enabled plan and a judge; a verified reference is also required except for sample generation. Supply model_keys or providers; omitting both runs…

  Register a saved schema for relational synchronization to PostgreSQL, MySQL or SQLite. Requires owner and a sync-enabled plan. Starts a billed classification job when available; returns database ID, classification_job_id or…

• assign_sync_host

  Assign or clear the host provisioning a database sync. Requires owner and a sync-enabled plan. host accepts a connected host ID/name; null unassigns it. Assignment may create the physical database and start synchronization automatically…

• classify_database_model

  Start a billed analysis proposing database keys, SQL types, indexes and relationship ownership on a linked schema. Requires editor. Registration already starts the initial pass; use this after relevant edits. Incremental scope covers new…

• delete_database_sync

  Delete a database registration and its queued deltas, stopping its feed. Requires owner and a sync-enabled plan; no LLM call. External replica tables remain untouched. Entity state and schema database flags remain by default…

• get_database_setup_instructions

  Return non-secret install, browser-confirmed pairing and run instructions for an ee-database sync client. Requires owner and a sync-enabled plan; no LLM call and no credential is issued or exposed to the MCP client. Run pair_command on…

• fetch_database_deltas

  Read the next ordered window of SQL deltas and canonical payloads for a database sync. claim=false is replayable; claim=true leases the window for 120 seconds. Apply a claimed window transactionally, including schema deltas, before…

• ack_database_deltas

  Acknowledge every delta through up_to_id after successful application, releasing its lease. Acknowledgement can permanently purge delivered deltas and entity state according to registration options; never acknowledge unapplied or failed…

• sync_records_to_database

  Validate and inject stored or supplied enrichment output into the entity layer and linked syncs. May incur semantic-resolution cost. record_id alone reuses its output; adding structured_output creates a new derived record. Without…

• list_models

  List available model keys, nominal capabilities, languages, strategies, auto-selected defaults and organization profile_limits. Use when choosing explicit models or checking plan limits; ordinary calls may omit models or use auto without…

• enrich_entity

  Enrich one entity against exactly one of schema_id or target_schema, returning structured output, record_id, costs and any database outcome. Read get_schema's input_contract first (published version when linked); never invent preserve…

• retry_expertises

  Retry only an existing record's failed expertise domains, then update its output and attempt the run's fusion/synchronization. Billed for retried work. Requires failed_expertises on that record (get_record); a surviving successful sibling…

• merge_records

  Fuse two or more records of the same entity into a new arbitration record. Without arbitration_model use voting, median and union rules; with an arbiter, conflicts may incur LLM cost. Returns output, conflicts, fusion metadata and a new…

• get_job_status

  Read a job's status, progress and compact terminal summary with persisted record IDs. Status is pending, running, paused, completed, failed or cancelled. Relay pause questions with answer_job_question. include_result=true returns full…

• cancel_job

  Request cancellation of a pending, running or paused LLM job. In-flight model calls may finish and persist records; remaining work is skipped. Cancellation does not roll back records or database writes. Read get_job_status and…

• answer_job_question

  Resume a paused job with answers to the questions returned under pause. answers maps question IDs to {option_ids: [...], text: ...}; omitted questions use defaults. Relay consequential unanswered choices to the user unless those defaults…

• list_records

  List compact, paginated records in your organization, most recent first. Filter by job_id to retrieve persisted outputs of an asynchronous workflow; type, success, model and search further narrow the result. Both per-model enrichment and…

• get_record

  Read one persisted record's structured_output, entity_input_data, validation errors, expertise verdicts and metrics. failed_expertises and partial identify incomplete work even when output exists; use retry_expertises only on a record…

• get_stats

  Read organization-wide record totals, success rate, tokens and cost summary. No LLM call. This tool has no job filter; use list_records(job_id=...) for a particular run and benchmark tools for comparative quality/cost/speed scores.

• generate_sample

  Generate editable sample JSON from a free-text request for schema authoring. Without attachments, use model knowledge and optional web search; with attachments, extract from the sources only (search does not relax that rule). Each sample…

• list_schemas

  List saved schemas in your organization, pinned first. Returns compact summaries with IDs, names and links; no LLM call. Use get_schema to inspect a chosen schema and its input contract, or get_schema_part for a targeted edit. For a…

• create_schema_from_sample

  Generate and auto-save a schema from reviewed samples, returning schema_id, schema content and record links. Supply entity_samples (or samples_csv), sample_record_id, or both; explicit samples override stored JSON while attachment…

• save_schema

  Save a directly authored schema and return its ID and link. Requires editor; no LLM call or generation charge. schema_content is a JSON Schema 2020-12 document in Entity Enricher's supported dialect: title, type='object', properties…

• update_schema

  Edit a saved schema's metadata or replace its full schema_content without an LLM call. Requires editor. Only supplied values change. For one property, prefer update_schema_property, add_schema_property or move_schema_property…

• get_schema_part

  Read only the schema fragment needed for an edit. Omit path for the root/type index; use '$defs.X' or '$enums.X' for a definition, an object path for its subtree, or a leaf path for its property card and relations. Dot-separated paths use…

• get_enum_candidates

  List observed values outside each open enum's current vocabulary, with counts from recent enrichment records. No LLM call. Use the report to propose admitted members or rejected_values, or close a vocabulary only when it is exhaustive…

  Edit or remove one property by path without replacing the full schema. Requires editor; no LLM call. Only supplied fields change; null clears an entry in flags. Server validation rejects or normalizes invalid combinations and reports…

• add_schema_property

  Add a property under the root (parent_path=''), an object path or '$defs.X'. Accepts a scalar, nested object or reference to an existing $defs entity or $enums vocabulary. Requires editor; no LLM call. Omitted nullable means required at…

• move_schema_property

  Move one property into the root, an object path or '$defs.X', preserving its flags and expertise. Requires editor; no LLM call. Moving into a definition changes every usage site. An identity composition naming the property is re-spelled…

• resolve_unify_proposal

  Resolve one pending entity-type unification proposal from get_schema. action='accept' maps the proposed site onto the winning $def; field_map overrides proposed correspondences. Unmapped fields are retained as nullable; other usages of…

• nest_schema_region

  Materialize an entity region from get_schema's x-entityMap. Ordinary flat members (e.g. product_id, product_name on an order line) move into a new object named after the region, regions hanging from it move along (nest them in turn inside…

• publish_schema

  Publish a database-linked schema's working copy as the contract used by enrichment and replicas. A newly linked schema sends nothing until first publication; unlinked drafts cannot be published. Requires editor; no LLM call. Call…

• delete_schema

  Soft-delete a saved schema by UUID. Requires editor; no LLM call. Restoration and permanent deletion are available in the web app, not through this tool. Returns the deletion outcome.

• get_semantic_concept

  Read one concept's aliases, identity source keys, linked records and nearest neighbors within its own type/model slice. Record links are capped; records_truncated signals omitted links. neighbors_limit=0 skips neighbors. Use returned…

• probe_semantic_concept

  Preview identity resolution without adding a concept or increasing its usage. Requires editor; uncached resolution may call embeddings and the identity judge. Returns exact_hit, match or no_match, the matched concept and neighbors. Probe…

• add_semantic_concept

  Add an identity concept at zero usage, or add text as an alias using alias_of. Requires editor; resolution may incur embedding/judge cost. Probe first; if the text already resolves to an incumbent, offer that concept instead of blindly…

• update_concept_alias

  Remove or promote a concept alias using alias IDs from get_semantic_concept. Requires editor; no LLM call. action='remove' stops that surface form resolving to this concept; removing the last alias is refused. action='set_canonical'…

• import_semantic_concepts

  Resolve 1..1000 texts against one concept type. mint=false returns exact/matched/would_mint outcomes without minting; mint=true creates misses and requires owner (reporting requires editor). Resolution can call embeddings and the identity…
