Convert a JSON array of objects into a Markdown table. Automatically detects columns, aligns headers, and fills missing keys with empty cells. Use when an agent needs to present structured data — tool results, model comparisons, test reports — as a readable table in a response or document.
AI agents call format_table to retrieve information from Ia Qa Com/mcp llm and RAG testing Dev/QA toolbox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
input | string | — | JSON array of objects to convert to a Markdown table |
columns | array | — | Column names and order (default: all keys from first row) |
Parameters from the server's own tool schema.
This tool performs data formatting and transformation only. It reads structured JSON input and outputs formatted Markdown without creating, modifying, deleting, or executing any operations. It is a pure display/rendering utility with no capability to alter underlying data or trigger external operations. The blast radius of misuse is negligible — worst case is a poorly formatted table.
From the tool's definition Tool converts JSON data into Markdown table format. The description states it 'converts', 'detects columns', 'aligns headers', and 'fills missing keys' — purely data transformation and presentation operations with no side effects.
Documented attack patterns abuse exactly the kind of access format_table gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ia Qa Com/mcp llm and RAG testing Dev/QA toolbox, and nothing reaches the server without passing your rules. This is the rule we recommend for format_table:
{
"version": "1",
"default": "deny",
"tools": {
"format_table": {}
}
}format_table is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Convert a JSON array of objects into a Markdown table. Automatically detects columns, aligns headers, and fills missing keys with empty cells. Use when an agent needs to present structured data — tool results, model comparisons, test reports — as a readable table in a response or document. It is categorised as a Read tool in the Ia Qa Com/mcp llm and RAG testing Dev/QA toolbox MCP Server, which means it retrieves data without modifying state.
format_table accepts 2 parameters: input, columns. The full parameter table on this page comes from the server's own tool schema.
Register the Ia Qa Com/mcp llm and RAG testing Dev/QA toolbox MCP server in PolicyLayer and add a rule for format_table: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ia Qa Com/mcp llm and RAG testing Dev/QA toolbox. Nothing to install.
format_table is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the format_table rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for format_table. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
format_table is provided by the Ia Qa Com/mcp llm and RAG testing Dev/QA toolbox MCP server (ia-qa/api). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ia Qa Com/mcp llm and RAG testing Dev/QA toolbox, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
