Overview

AI-generated overview

Remote ASN.1 tooling that lets an assistant validate ASN.1 schemas and compile them into source code and codecs.

What you can do
  • Validate ASN.1 schema definitions, returning informational messages, warnings and errors
  • Compile ASN.1 schemas into executable source code and codecs such as DER, PER, UPER or BER for a chosen programming language
  • Report compilation status, error messages and the generated files
When to use it
Useful when working with ASN.1 specifications and you want an assistant to check a schema for syntax or semantic problems, or to generate encoder/decoder code from it without leaving the conversation.
Requirements
A remote MCP endpoint at asn1.io over streamable HTTP; no packages, environment variables or headers are declared. Network access to that endpoint is needed.
Before you install
No authentication is declared, so avoid sending confidential or proprietary schemas to a third-party service. Compilation produces generated source files, which should be reviewed before use.

Installation

In SourceWeft

  1. Open Asn1 Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.OSSNokalva%2Fasn1-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

{
  "mcpServers": {
    "asn1": {
      "type": "http",
      "url": "https://asn1.io/mcp"
    }
  }
}

Tools

2

compile_asn1_schema

Compiles ASN.1 schema definitions into executable source code. Use this tool whenever a user asks to generate code, compile an ASN.1 schema, or create a codec (e.g., DER, PER, UPER, BER) for a specific programming language. The tool returns the compilation status, error messages, and files containing the generated source code.

ParameterscodecuserIdfileNameschemaContenttargetLanguage

validate_asn1_schema

Validates ASN.1 schema definitions syntax and semantics. Use this tool whenever a user asks to validate, check, or verify an ASN.1 schema without generating source code. The tool returns a list of messages (informational, warnings, and errors).

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
