Shared MCP Tools - QuantSpace

Overview

Each hosted MCP server exposes a server-specific research surface plus shared helper tools. The helpers cover discovery, health checks, result handling, artifacts, environment inspection, and optional table/database introspection.

Common Tools

Tool	Description
`agent_docs`	Returns structured MCP documentation for agents: overview, tools, environment, database notes, and examples.
`runtime_health`	Returns runtime health and readiness diagnostics.
`deployment_info`	Returns deployed URL, runtime profile, storage, and database configuration.
`env_describe`	Shows required and optional environment variables with present/missing status and masked previews.
`db_list_tables`	Read-only table/view introspection when database access is configured.
`result_preview`	Previews a stored result without transferring the full payload.
`result_get`	Reads a stored result when the full payload is needed.
`save_tool_result`	Persists a stored or raw payload as a scoped downloadable artifact.
`artifact_get_meta`	Fetches metadata for a scoped artifact.
`artifact_read_chunk`	Reads a scoped artifact in base64 chunks for MCP-only clients.
`artifact_get_download_url`	Builds a download URL for a scoped artifact when URL generation is enabled.

Result and Artifact Flow

Large tabular or nested outputs may be compacted into a stored result_id. Inspect the result with result_preview or result_get. To make a stored or raw payload downloadable, call save_tool_result, then use artifact_get_meta, artifact_read_chunk, or artifact_get_download_url.

{
  "request": {
    "result_id": "<result-id>",
    "filename": "factor_output.json"
  }
}

Health and Deployment Discovery

Use runtime_health before long runs and deployment_info when you need to confirm the effective MCP URL, runtime profile, storage settings, or database configuration.

  "request": {}
}

Admin/auth mutation tools and raw database query tools may exist in some deployments but are operator tools, not default client workflow tools.
