Textavia MCP

@textavia/mcp exposes the Textavia developer tool registry through the Model Context Protocol. It lets MCP-capable agents call local Textavia utilities for JSON, Base64, CSV, Markdown tables, regex checks, hashing, text cleanup, case conversion, random values, timestamps, and privacy scrubbing.

The MCP package is a thin stdio server over the same registry and executors used by the textavia / txv CLI. It is designed for agents that need dependable local text and data transformations without copying user data into a web app.

Quick Start

npx @textavia/mcp

Or install it globally:

npm install -g @textavia/mcp
textavia-mcp

Use this MCP server config in clients that accept stdio server definitions:

{
  "mcpServers": {
    "textavia": {
      "command": "npx",
      "args": ["-y", "@textavia/mcp"]
    }
  }
}

If you install globally, you can use the binary directly:

{
  "mcpServers": {
    "textavia": {
      "command": "textavia-mcp"
    }
  }
}

What It Exposes

MCP tool names are generated from Textavia registry IDs. The package keeps the Textavia namespace and uses underscore-separated operation names:

MCP tool	Backing registry tool	Typical use
textavia.json_format	dev.json.format	Pretty-print JSON from text or a file.
textavia.json_validate	dev.json.validate	Validate JSON and return diagnostics.
textavia.json_repair	dev.json.repair	Repair common malformed JSON output.
textavia.json_to_types	dev.json.to-types	Generate TypeScript types from sample JSON.
textavia.base64_encode	encoding.base64.encode	Encode text or bytes as Base64.
textavia.base64_decode	encoding.base64.decode	Decode Base64 to text or bytes.
textavia.csv_to_json	data.csv.to-json	Convert CSV text to JSON rows.
textavia.markdown_table_to_json	data.markdown.table-to-json	Convert Markdown tables to JSON.
textavia.regex_test	dev.regex.test	Test a JavaScript regex against input text.
textavia.text_clean	text.clean	Collapse whitespace and normalize pasted text.
textavia.text_privacy_scrub	text.privacy-scrub	Redact emails, phones, URLs, IPs, and similar data.
textavia.case_slug	case.slug	Create URL slugs from titles or labels.
textavia.hash_sha256	dev.hash.sha256	Compute SHA-256 digests for text or files.
textavia.random_uuid	random.uuid	Generate UUIDs.

Each MCP tool accepts the same argument shape:

{
  "input": "text to process",
  "file": "optional/path/to/file.txt",
  "options": {
    "toolSpecificOption": "value"
  }
}

Use input for direct text. Use file when the agent should read from disk. Options are validated against each tool's registry schema.

Example Agent Calls

Format JSON:

{
  "input": "{\"name\":\"Ada\",\"tools\":[\"Textavia\"]}",
  "options": {
    "indent": 2
  }
}

Convert CSV to JSON:

{
  "input": "name,role\nAda,engineer",
  "options": {
    "delimiter": ","
  }
}

Test a regex:

{
  "input": "Textavia 2026",
  "options": {
    "pattern": "\\d+",
    "flags": "g"
  }
}

Scrub private text:

{
  "input": "Email [e-mail] or call 555-123-4567"
}

Safety Model

• Standard tools run locally in the MCP server process.
• The published stdio command uses local-first defaults.
• Network-required tools are hidden by default.
• Tool arguments are parsed with Zod schemas before execution.
• File input is explicit through the MCP file argument.
• The package does not include postinstall scripts.
• The package does not require telemetry to run.

The library API exports createTextaviaMcpServer, buildMcpRegistry, and executeMcpTool for hosts that want tighter filtering, category selection, network gating, filesystem policy, or maximum input size limits.
