Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools · 2 exposed · ~626 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
shape_file_to_json ~284

Read a local text file (key: value notes, .csv, .tsv or a Markdown table) and return typed JSON. Use this when the data is in a file on this computer, so you don't have to paste it. The file is only read, never changed. Do not use it for Excel (.xlsx), PDF or other binary files, for files that are already JSON, or for app logs. path: full path to a UTF-8 text file, up to 5 MB. format: "auto" (default) picks for you. Or force "kv" (key: value or key=value lines, a blank line starts a new record), "csv" (comma, semicolon, tab or | separated, first row is the header) or "markdown" (a | pipe | table, first row is the header). Returns {"format": <format used>, "data": <JSON>}, the same as shape_text_to_json.

NameTypeReqDescription
formatstring–Input format. "auto" picks for you; "kv" = key: value lines, "csv" = CSV/TSV, "markdown" = a pipe table.
pathstringyesFull path to a UTF-8 text file (.txt, .csv, .tsv, .md), up to 5 MB.

No examples provided.

shape_text_to_json ~342

Turn pasted text (key: value notes, CSV/TSV or a Markdown table) into typed JSON. Use this when you have plain-text records or a table in the conversation and need clean JSON you can trust, without guessing values yourself. It is plain code, not an AI model, so the same text always gives the same JSON and nothing is made up. Do not use it when the text is already JSON, is nested data, is app logs, or is a file on disk (use shape_file_to_json for files). format: "auto" (default) picks for you. Or force "kv" (key: value or key=value lines, a blank line starts a new record), "csv" (comma, semicolon, tab or | separated, first row is the header) or "markdown" (a | pipe | table, first row is the header). Returns {"format": <format used>, "data": <JSON>}. data is a list of records for CSV and tables. For key: value text it is one object, or a list when blank lines split it into several records. Keys become lower_snake_case. Numbers become numbers, yes/no and true/false become booleans, empty or "null" becomes null.

NameTypeReqDescription
formatstring–Input format. "auto" picks for you; "kv" = key: value lines, "csv" = CSV/TSV, "markdown" = a pipe table.

Common questions

What is the json-shaper-lite MCP server?

json-shaper-lite is an MCP server listed in the public MCP registry as io.github.tidybytetools/json-shaper-lite. Turn key: value notes, CSV/TSV and Markdown tables into typed JSON. Plain code, no AI, runs locally. This page covers its PyPI package (json-shaper-lite).

Is the json-shaper-lite MCP server safe to use?

json-shaper-lite scores 66 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the json-shaper-lite MCP server expose?

json-shaper-lite exposes 2 tools: shape_text_to_json, shape_file_to_json. Their descriptions and schemas cost roughly 626 tokens of context every time the server is loaded.

Is the json-shaper-lite MCP server still maintained?

json-shaper-lite is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the json-shaper-lite MCP server under?

json-shaper-lite declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
