WHAT IT DOES

What workbook_csv_parse does on Ainumbers Mcp Apps

AI agents call workbook_csv_parse to retrieve information from Ainumbers Mcp Apps without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`csv`	string	Yes	CSV text to parse.
`provenance`	object	—	Optional provenance metadata, only used when as_artifact is true. Never affects execution_hash.
`as_artifact`	boolean	—	When true, returns a full OpenChainGraph v0.4 artifact (policy_parameters/output_payload/execution_hash/provenance) via the same exportArtifact() path as the to

Parameters from the server's own tool schema.

RISK

Why workbook_csv_parse is rated Low

This tool parses and transforms input data (CSV text) into a structured representation. It performs no writes, deletions, financial operations, or external side effects — it is a pure data-parsing/transformation function. The server description explicitly states 'Read-only'. Severity is low as misuse is limited to returning parsed data.

FAQ

Questions about workbook_csv_parse

What does the workbook_csv_parse tool do? +

Parses CSV text with the SAME strict RFC 4180 parser as the tools/554 browser workbook -- quoted fields, embedded quotes/commas/newlines, CRLF -- and REJECTS malformed input rather than repairing it (deterministic beats forgiving for hash-stable digests). Numeric-looking and TRUE/FALSE cells are type-coerced; everything else stays a string. Returns the resulting A1-style cells (raw + evaluated value) plus the sheet's row/column extent, ready for workbook_evaluate or workbook_range_digest -- unless as_artifact is true, in which case it returns a full OCG v0.4 artifact instead (see as_artifact). It is categorised as a Read tool in the Ainumbers Mcp Apps MCP Server, which means it retrieves data without modifying state.

What parameters does workbook_csv_parse accept? +

workbook_csv_parse accepts 3 parameters: csv, provenance, as_artifact. Required: csv. The full parameter table on this page comes from the server's own tool schema.
