(2) You are working with nested serialization contexts where the same string passes through multiple layers — chain mode applies escapes in sequence and shows each transformation step so you can audit the layered output. DO NOT USE WHEN: the value is a number, boolean, or already-escaped content. Do not use for HTML entity encoding — use html_encoder which has a richer entity mode and context awareness. OVER ALTERNATIVES: prefer this over JSON.stringify (only handles JSON, no chain mode) and per-format escape libraries (no unified API, no chain transparency).","mcpDescription":"Escapes or unescapes strings for a target context. USE WHEN: embedding a string in JSON, SQL, HTML, regex, shell, URI, CSV, or XML, or unescaping output from one of those contexts. Chain mode applies multiple escapes in sequence (e.g., SQL inside JSON inside URI) — eliminates injection vulnerabilities from wrong escape ordering. INPUT: text, format, direction, optional chain array. OUTPUT: result string, optional per-step chain log. COST: 1 unit.","howTo":[{"step":"Choose format and direction","description":"Pick the target context (JSON, SQL, HTML, regex, shell, URI, CSV, XML) and direction (escape or unescape)."},{"step":"Enable chain mode (optional)","description":"Provide an ordered array like [sql, json, uri] to apply multiple escapes in sequence."},{"step":"Escape or unescape","description":"Click Run or press Ctrl+Enter. Output shows the result plus per-step transformations for chain mode."}],"faqs":[{"question":"What is chain mode for?","answer":"Nested serialization contexts require layered escaping. A SQL query embedded in a JSON API payload embedded in a URL parameter needs SQL → JSON → URI escaping in that order. Wrong order produces injection vulnerabilities. Chain mode applies the escapes correctly and shows every step."},{"question":"Why do HTML and XML have different escape rules?","answer":"HTML allows unescaped apostrophes in attribute values when the attribute is double-quoted. XML strictly requires escaping apostrophes in single-quoted attributes. The tool tracks both rules and applies the correct one based on the format you select."},{"question":"How does JSON escaping handle special characters?","answer":"Backslash, double-quote, and control characters (0x00-0x1F) are escaped per RFC 8259. Forward slash is not escaped by default (it is optional). Unicode characters above U+007F are passed through as-is unless you also chain through ASCII-only escaping."},{"question":"Can I use this tool via the MCP API?","answer":"Yes. The tool is registered on the obfus.link MCP server at https://obfus.link/mcp. Call it from any MCP-compatible agent with a Shared Payment Token. The MCP tool name matches the snake_case slug shown in the integration snippet."}],"workflowChains":{"live":[],"planned":[]},"tags":["escape","unescape","json","sql","html","regex","shell","uri"],"tddVerified":true,"mcpCostUnits":1}}
