Reference the current Chat4U MCP tools, their public parameters, and their read or approval-gated behavior.

What you’ll accomplish

Use the catalog to choose a read first, then prepare a change only when the project policy and approval flow allow it. Tool discovery itself is role filtered.

Finish with: The smallest tool family needed for your task

This is the current registered MCP tool catalog. The server filters tools by the connection's role and capability policy; seeing a name in this reference does not guarantee it is available to a particular connection.

All IDs below are UUIDs. Project-scoped reads require project_id unless the tool can derive the project from an agent_id or datasource_id. Read results are safe/aggregate views, not raw content exports.

Workspace and projects — read

Tool	Public parameters	Purpose
`chat4u_workspace_get`	none	Active workspace and resource counts.
`chat4u_projects_list`	none	Projects in the credential's workspace.
`chat4u_project_get`	`project_id`	Current project configuration.
`chat4u_project_health_snapshot`	`project_id`, optional `lookback_days` (default 30)	Bounded operational health snapshot.
`chat4u_project_audit_configuration`	`project_id`, optional `agent_id`, `limit` (default 50)	Deterministic configuration-gap audit.
`chat4u_project_available_models`	`project_id`	Model tiers and models available to the project.

Agents and knowledge coverage — read

Tool	Public parameters	Purpose
`chat4u_agents_list`	`project_id`	Agents in an eligible project.
`chat4u_agent_get`	`project_id`, `agent_id`	One agent's current configuration.
`chat4u_agent_knowledge_coverage`	`project_id`, `agent_id`	Aggregate citation coverage for an agent.
`chat4u_agent_prompt_summary`	`project_id`, `agent_id`	Safe prompt-layer metadata; internal instructions are excluded.

Datasources — read

Tool	Public parameters	Purpose
`chat4u_datasources_list`	`project_id`	Safe source metadata and ingestion state.
`chat4u_datasource_get`	`project_id`, `datasource_id`	One source's safe metadata and state.
`chat4u_datasource_run_status`	`project_id`, `datasource_id`, optional `limit` (default 10)	Bounded ingestion-run status without source contents or raw errors.
`chat4u_datasource_analyze_health`	`project_id`, optional `datasource_id`	Deterministic health classification.
`chat4u_datasources_rank_attention`	`project_id`, optional `start_date`, `end_date`, `limit` (default 20)	Rank sources using operational health and bounded citation evidence.

Aggregate insights — read

Tool	Public parameters	Purpose
`chat4u_insights_read`	`project_id`, optional `agent_id`, `limit` (default 5)	Cached aggregate intelligence.
`chat4u_insights_read_overview`	`project_id`, optional `agent_id`, `start_date`, `end_date`	Bounded aggregate outcomes.
`chat4u_insights_read_patterns`	`project_id`, optional `agent_id`, `start_date`, `end_date`	Aggregate topics, intents, and sentiment.
`chat4u_insights_quality_gaps`	`project_id`, optional `agent_id`, `start_date`, `end_date`, `limit` (default 10)	Aggregate unanswered-topic and knowledge-gap evidence.
`chat4u_insights_compare_performance`	`project_id`, optional `agent_id`, `current_start_date`, `current_end_date`, `baseline_start_date`, `baseline_end_date`	Compare two bounded periods.
`chat4u_insights_connect_dots`	`project_id`, optional `agent_id`, `comparison_label`	Sanitized evidence across aggregates, source health, and configuration.

Small cohorts may return insufficient_data. None of these tools return raw conversations, message examples, or record IDs.

Changes — approval-gated

Before calling a change tool

Use an eligible project ID returned by Chat4U
Inspect the proposed target and arguments
Expect confirmation or strong approval when required
Check action status instead of assuming execution

Every tool in this section requires client_request_id plus the listed parameters. Its first call prepares a proposal; it does not mutate state. Approval is presented through a supported client form or a first-party approval page. Resume the same unchanged request with that ID when the client asks, and verify the returned action status before treating it as complete.

Area	Tools and public parameters
Project	`chat4u_project_update(project_id, changes)`; `chat4u_project_regenerate_business_context(project_id)`; `chat4u_project_delete(project_id)`.
Agents	`chat4u_agent_create(project_id, name, datasource_ids, optional configuration)`; `chat4u_agent_update(project_id, agent_id, changes)`; `chat4u_agent_publish(project_id, agent_id)`; `chat4u_agent_activate(project_id, agent_id)`; `chat4u_agent_deactivate(project_id, agent_id)`; `chat4u_agent_delete(project_id, agent_id)`.
URL and text sources	`chat4u_datasource_create(project_id, url, optional name, scrape_mode, crawl_depth, max_pages, include_sitemap_fallback, include_patterns, exclude_patterns, is_recurring, recurring_interval_hours, agent_ids)`; `chat4u_datasource_create_text(project_id, content, optional name, agent_ids)`; `chat4u_datasource_update(project_id, datasource_id, changes)`; `chat4u_datasource_update_url(project_id, datasource_id, source_url)`; `chat4u_datasource_start(project_id, datasource_id)`; `chat4u_datasource_resync(project_id, datasource_id, optional hard)`; `chat4u_datasource_cancel(project_id, datasource_id)`; `chat4u_datasource_delete(project_id, datasource_id)`.

Text source content is limited to 1–12,000 characters. A URL change must use chat4u_datasource_update_url; URL connection, URL changes, starts, and resyncs require first-party authority confirmation. Deletion, publication, and project deletion use a stronger approval path.

Action status — read

chat4u_action_get(action_id) returns the status of an action in the authenticated workspace. Use it to report whether a proposal is pending, approved, rejected, expired, executed, or failed; do not infer success merely because a proposal was created.
