Implementation Reference

• otp_mcp/tool.py:165-181 (handler)

  The main handler function for the 'delete_token' MCP tool. It is decorated with @mcp.tool() which handles registration. Deletes OTP tokens from the database that match the given pattern.

  @mcp.tool()
  async def delete_token(pattern: str) -> str:
      """
      Delete an OTP token matching the pattern.
  
      Args:
          pattern: Token pattern (part of the name or token number)
      """
      db = get_token_db()
      tokens = find_tokens(pattern)
      if not pattern:
          raise ToolError("Pattern cannot be empty.")
      if not tokens:
          raise ToolError("No OTP tokens found.")
      for token in tokens:
          db.delete()
      return f"{len(tokens)} tokens deleted."

• otp_mcp/tool.py:36-49 (helper)

  Helper function used by delete_token (and other tools) to find OTP tokens matching a search pattern.

  def find_tokens(pattern: str) -> list[Token]:
      """
      Find tokens matching the given pattern.
      """
      db = get_token_db()
      if not pattern:
          return db.get_tokens()
      tokens_list = []
      pattern = pattern.lower()
      for token in db.get_tokens():
          tmp = str(token).lower().strip()
          if pattern in tmp or pattern == f"{token.rowid}#":
              tokens_list.append(token)
      return tokens_list
